-.Sh DESCRIPTION
-The crypto library maintains a global list of
-.Vt ENGINE
-objects.
-.Pp
-.Fn ENGINE_add
-appends
-.Fa e
-to the end of the list
-and increments its structural reference count by 1.
-A unique identifier and a name of
-.Fa e
-have to be set with
-.Fn ENGINE_set_id
-and
-.Fn ENGINE_set_name
-before calling this function.
-.Fn ENGINE_add
-fails if the list already contains an
-.Vt ENGINE
-with the same identifier.
-.Pp
-.Fn ENGINE_remove
-removes
-.Fa e
-from the list.
-If successful, it calls
-.Xr ENGINE_free 3
-on
-.Fa e .
-.Pp
-.Fn ENGINE_cleanup
-calls
-.Xr ENGINE_finish 3
-on all
-.Vt ENGINE
-objects that were selected as default engines, for example using the
-functions documented in the
-.Xr ENGINE_set_default 3
-and
-.Xr ENGINE_get_default_RSA 3
-manual pages, and it calls
-.Fn ENGINE_remove
-on all
-.Vt ENGINE
-objects that were added to the global list with
-.Fn ENGINE_add .
-Calling this function is required at the end of each program using
-.Fn ENGINE_add ,
-even if no engines are explicitly registered or used.
-.Pp
-.Fn ENGINE_get_first
-and
-.Fn ENGINE_get_last
-provide access to the first and last
-.Vt ENGINE
-object on the list, respectively.
-Unless the list is empty, they increment the structural reference
-count of the retrieved object by 1.
-.Pp
-.Fn ENGINE_get_next
-and
-.Fn ENGINE_get_prev
-support iteration of the list.
-They always call
-.Xr ENGINE_free 3
-on
-.Fa e .
-Unless the end of the list is reached, they increment the structural
-reference count of the retrieved object by 1.
-.Pp
-.Fn ENGINE_by_id
-searches the list for an
-.Vt ENGINE
-object with a matching
-.Fa id .
-If found, it increments the structural reference count of the
-retrieved object by 1.
-If
-.Dv ENGINE_FLAGS_BY_ID_COPY
-was set on
-.Fa e
-with
-.Xr ENGINE_set_flags 3 ,
-it returns a shallow copy of the object rather than incrementing
-the reference count and returning a pointer to the original.
-.Sh RETURN VALUES
-.Fn ENGINE_add ,
-.Fn ENGINE_set_id ,
-.Fn ENGINE_set_name ,
-and
-.Fn ENGINE_remove
-return 1 on success or 0 on error.
-.Fn ENGINE_set_id
-and
-.Fn ENGINE_set_name
-can only fail if the supplied
-.Fa id
-or
-.Fa name
-is
-.Dv NULL .
-.Pp
-.Fn ENGINE_get_id
-and
-.Fn ENGINE_get_name
-return a pointer to an internal string
-representing the identifier and the name of
-.Fa e ,
-respectively.
-.Pp
-.Fn ENGINE_get_first
-and
-.Fn ENGINE_get_last
-return an
-.Vt ENGINE
-object or
-.Dv NULL
-if the list is empty.
-.Pp
-.Fn ENGINE_get_next
-and
-.Fn ENGINE_get_prev
-return an
-.Vt ENGINE
-object or
-.Dv NULL
-when the end of the list is reached.
-.Pp
-.Fn ENGINE_by_id
-returns an
-.Vt ENGINE
-object or
-.Dv NULL
-if no matching object is found.

-.Sh DESCRIPTION
-.Fn ENGINE_ctrl
-calls the built-in or user-defined
-.Fa cmd
-for the engine
-.Fa e ,
-passing the arguments
-.Fa i
-and
-.Fa p .
-.Pp
-User-defined commands can be used before
-.Xr ENGINE_init 3
-to provide data required for initialization
-or at any time to modify the behaviour of an engine.
-.Pp
-Most built-in commands operate on user-defined commands installed with
-.Fn ENGINE_set_cmd_defns ,
-either using the
-.Fa p
-argument to indicate the user-defined command with the command name
-.Fa cmd_name
-or using the
-.Fa i
-argument to indicate the user-defined command with the command number
-.Fa cmd_num .
-The
-.Fa cmd
-arguments to call the built-in commands are as follows:
-.Bl -tag -width Ds
-.It Dv ENGINE_CTRL_GET_CMD_FLAGS
-Return the
-.Fa cmd_flags
-of the user-defined command with the number
-.Fa i ,
-or a number less than or equal to 0 if an error occurs or
-the command number does not exist.
-A return value of 0 indicates failure if
-.Fa e
-is
-.Dv NULL
-or has a reference count of 0, or success if
-.Fa e
-is valid.
-.It Dv ENGINE_CTRL_GET_CMD_FROM_NAME
-Return the positive command number
-of the user-defined command with the name
-.Fa p ,
-or a number less than or equal to 0 if an error occurs or no
-matching name is found.
-.It Dv ENGINE_CTRL_GET_DESC_FROM_CMD
-Copy the description of the user-defined command with the number
-.Fa i
-into the buffer
-.Fa p
-and NUL-terminate it.
-It is the responsibility of the caller to make sure that the buffer
-.Fa p
-is large enough, either by calling
-.Dv ENGINE_CTRL_GET_DESC_LEN_FROM_CMD
-first or using knowledge about the array passed to
-.Fn ENGINE_set_cmd_defns .
-The return value is the number of bytes written
-.Em including
-the terminating NUL byte, or a number less than or equal to 0
-if an error occurs.
-.It Dv ENGINE_CTRL_GET_DESC_LEN_FROM_CMD
-Return the length in bytes
-.Em excluding
-the terminating NUL byte
-of the description of the user-defined command with the number
-.Fa i ,
-or a number less than or equal to 0 if an error occurs.
-A return value of 0 indicates failure if
-.Fa e
-is
-.Dv NULL
-or has a reference count of 0, or success if
-.Fa e
-is valid.
-.It Dv ENGINE_CTRL_GET_FIRST_CMD_TYPE
-Return the positive command number
-of the first user-defined command installed with
-.Fn ENGINE_set_cmd_defns
-or a number less than or equal to 0 if an error occurs or no
-user-defined command has been installed.
-.It Dv ENGINE_CTRL_GET_NAME_FROM_CMD
-Copy the name of the user-defined command with the number
-.Fa i
-into the buffer
-.Fa p
-and NUL-terminate it.
-It is the responsibility of the caller to make sure that the buffer
-.Fa p
-is large enough, either by calling
-.Dv ENGINE_CTRL_GET_NAME_LEN_FROM_CMD
-first or using knowledge about the array passed to
-.Fn ENGINE_set_cmd_defns .
-The return value is the number of bytes written
-.Em including
-the terminating NUL byte, or a number less than or equal to 0
-if an error occurs.
-.It Dv ENGINE_CTRL_GET_NAME_LEN_FROM_CMD
-Return the length in bytes
-.Em excluding
-the terminating NULL byte
-of the name of the user-defined command with the number
-.Fa i ,
-or a number less than or equal to 0 if an error occurs.
-A return value of 0 indicates failure if
-.Fa e
-is
-.Dv NULL
-or has a reference count of 0, or success if
-.Fa e
-is valid.
-.It Dv ENGINE_CTRL_GET_NEXT_CMD_TYPE
-Return the positive command number of the next user-defined command
-after the user-defined command with the number
-.Fa i ,
-or a number less than or equal to 0 if an error occurs or if
-.Fa i
-is the last user-defined command.
-Together with
-.Dv ENGINE_CTRL_GET_FIRST_CMD_TYPE ,
-this can be used to iterate the user-defined commands installed with
-.Fn ENGINE_set_cmd_defns .
-.It Dv ENGINE_CTRL_HAS_CTRL_FUNCTION
-Return 1 if
-.Fa e
-has its own
-.Fa ctrl_f
-installed with
-.Fn ENGINE_set_ctrl_function
-or 0 otherwise.
-.El
-.Pp
-.Fn ENGINE_ctrl_cmd
-translates the
-.Fa cmd_name
-of a user-defined command to a
-.Fa cmd
-number and calls
-.Fn ENGINE_ctrl
-on it.
-If
-.Fa cmd_optional
-is non-zero, lack of a
-.Fa ctrl_f
-in
-.Fa e
-and translation failure with
-.Dv ENGINE_CTRL_GET_CMD_FROM_NAME
-are considered success, and the command has no effect.
-Otherwise, these problems cause
-.Fn ENGINE_ctrl_cmd
-to fail.
-.Pp
-Neither
-.Fn ENGINE_ctrl
-nor
-.Fn ENGINE_ctrl_cmd
-ever call the
-.Fa f
-callback, but merely pass it on as an argument to the engine-specific
-.Fa ctrl_f
-control function.
-It is up to
-.Fa ctrl_f
-how to use it, or alternatively to ignore it as well.
-.Pp
-.Fn ENGINE_ctrl_cmd_string
-translates the
-.Fa cmd_name
-of a user-defined command to a
-.Fa cmd
-number.
-If that command has the
-.Dv ENGINE_CMD_FLAG_NO_INPUT
-flag set,
-.Fa arg
-must be
-.Dv NULL
-and
-.Fn ENGINE_ctrl
-is called with
-.Fa i
-set to 0 and
-.Fa p
-set to
-.Dv NULL .
-Otherwise,
-.Fa arg
-must not be
-.Dv NULL .
-If the command accepts string input,
-.Fa i
-is set to 0 and
-.Fa arg
-is passed as the
-.Fa p
-argument to
-.Fn ENGINE_ctrl .
-Otherwise,
-.Fa arg
-is converted with
-.Xr strtol 3
-and passed as the
-.Fa i
-argument to
-.Fn ENGINE_ctrl ,
-setting
-.Fa p
-to
-.Dv NULL .
-.Pp
-.Fn ENGINE_set_ctrl_function
-installs
-.Fa ctrl_f
-as the engine-specific control function for
-.Fa e .
-Future calls to
-.Fn ENGINE_ctrl
-will call that function, passing on their arguments unchanged, if the
-.Fa cmd
-is not built-in to the library or if the
-.Dv ENGINE_FLAGS_MANUAL_CMD_CTRL
-flag is set in
-.Fa e .
-Let the
-.Fa ctrl_f
-return positive values on success or negative values on failure.
-Avoid return values of 0 because they cause dangerous ambiguity.
-In particular,
-.Fn ENGINE_ctrl_cmd
-and
-.Fn ENGINE_ctrl_cmd_string
-cannot be used with user-defined commands
-that may return 0 on success.
-.Pp
-.Fn ENGINE_set_cmd_defns
-install an array of command definitions in
-.Fa e .
-.Pp
-The structure
-.Vt ENGINE_CMD_DEFN
-has the following fields:
-.Bl -tag -width Ds
-.It Fa "unsigned int cmd_num"
-A positive, unique, monotonically increasing command number.
-Avoid using numbers below
-.Dv ENGINE_CMD_BASE .
-.It Fa "const char *cmd_name"
-The unique name of the command.
-.It Fa "const char *cmd_desc"
-A short description of the command.
-.It Fa "unsigned int cmd_flags"
-The bitwise OR of zero or more of the following flags:
-.Bl -tag -width Ds
-.It Dv ENGINE_CMD_FLAG_NUMERIC
-The command uses
-.Fa i .
-.It Dv ENGINE_CMD_FLAG_STRING
-The command uses
-.Fa p .
-.It Dv ENGINE_CMD_FLAG_NO_INPUT
-The command neither uses
-.Fa i
-nor
-.Fa p .
-.It Dv ENGINE_CMD_FLAG_INTERNAL
-This flag has no effect and is only provided for compatibility.
-.El
-.El
-.Pp
-The last element of
-.Fa defns
-does not specify a command, but must have a
-.Fa cmd_num
-of 0 and a
-.Fa cmd_name
-of
-.Dv NULL
-to indicate the end of the array.
-.Sh RETURN VALUES
-For
-.Fn ENGINE_ctrl ,
-positive return values indicate success and negative return values
-indicate failure.
-The meaning of a zero return value depends on the particular
-.Fa cmd
-and may indicate both success and failure, which is pathetic.
-.Pp
-Regardless of the
-.Fa cmd ,
-.Fn ENGINE_ctrl
-returns 0 if
-.Fa e
-is
-.Dv NULL
-or has a reference count of 0.
-This is quite unfortunate for commands like
-.Dv ENGINE_CTRL_GET_CMD_FLAGS
-where 0 may indicate success, so make sure
-.Fa e
-is valid before issuing a control command.
-.Pp
-For built-in commands except
-.Dv ENGINE_CTRL_HAS_CTRL_FUNCTION ,
-.Fn ENGINE_ctrl
-returns \-1 if
-.Dv ENGINE_FLAGS_MANUAL_CMD_CTRL
-is set but no
-.Fa ctrl_f
-has been installed with
-.Fn ENGINE_set_ctrl_function .
-.Pp
-For commands that are not built in,
-.Fn ENGINE_ctrl
-returns 0 if no
-.Fa ctrl_f
-has been installed with
-.Fn ENGINE_set_ctrl_function .
-.Pp
-.Fn ENGINE_cmd_is_executable
-returns 1 if the user-defined
-.Fa cmd
-is executable and has at least one of the flags
-.Dv ENGINE_CMD_FLAG_NUMERIC ,
-.Dv ENGINE_CMD_FLAG_STRING ,
-and
-.Dv ENGINE_CMD_FLAG_NO_INPUT
-set, or 0 otherwise.
-.Pp
-.Fn ENGINE_ctrl_cmd
-and
-.Fn ENGINE_ctrl_cmd_string
-return 1 on success or 0 on error.
-.Pp
-.Fn ENGINE_set_ctrl_function
-and
-.Fn ENGINE_set_cmd_defns
-always return 1.
-.Pp
-.Fn ENGINE_get_ctrl_function
-returns a pointer to the function
-.Fa ctrl_f
-installed with
-.Fn ENGINE_set_ctrl_function ,
-or
-.Dv NULL
-if none has been installed.
-.Pp
-.Fn ENGINE_get_cmd_defns
-returns the array of command definitions installed in
-.Fa e
-or
-.Dv NULL
-if none is installed.

-.Sh DESCRIPTION
-These functions retrieve the current default
-.Vt ENGINE
-implementing the respective algorithm.
-.Pp
-If a default engine was previously selected,
-.Xr ENGINE_init 3
-is called on it again and it is used.
-Otherwise, these functions inspect the engines registered
-with the functions documented in
-.Xr ENGINE_register_RSA 3
-in the order of the table for the respective algorithm.
-If an inspected engine is already successfully initialized,
-.Xr ENGINE_init 3
-is called on it again and it is used as the new default.
-Otherwise, unless the global flag
-.Dv ENGINE_TABLE_FLAG_NOINIT
-is set,
-.Xr ENGINE_init 3
-is tried on it.
-If it succeeds, that engine is used as the new default.
-If it fails or if
-.Dv ENGINE_TABLE_FLAG_NOINIT
-is set, inspection continues with the next engine.
-.Pp
-The global flag can be set by calling
-.Fn ENGINE_set_table_flags
-with an argument of
-.Dv ENGINE_TABLE_FLAG_NOINIT
-or cleared by calling it with an argument of 0.
-By default, the flag is not set.
-.Pp
-While all the other functions operate on exactly one algorithm,
-.Fn ENGINE_get_cipher_engine
-and
-.Fn ENGINE_get_digest_engine
-are special in so far as they can handle multiple algorithms,
-identified by the given
-.Fa nid .
-The default engine is remembered separately for each algorithm.
-.Pp
-Application programs rarely need to call these functions because
-they are called automatically when needed, in particular from
-.Xr RSA_new 3 ,
-.Xr DSA_new 3 ,
-.Xr EC_KEY_new 3 ,
-.Xr DH_new 3 ,
-.Xr EVP_CipherInit_ex 3 ,
-and
-.Xr EVP_DigestInit_ex 3 .
-.Sh RETURN VALUES
-These functions return a functional reference to an
-.Vt ENGINE
-object or
-.Dv NULL
-on failure, in particular when no engine implementing the algorithm
-is available, when
-.Xr ENGINE_init 3
-fails for all implementations,
-or when insufficient memory is available.
-Even when these functions fail, the application may still be able
-to use the algorithm in question because the built-in implementation
-is used in that case, if one is available.

-if any.
-In case of success, it also increments both the structural
-and the functional reference count by 1.
-If no

-except that it increments both the structural and the functional
-reference count by 1.
-.Pp
-.Fn ENGINE_finish
-decrements the functional reference count by 1.
-When it reaches 0, it calls the

-.Sh DESCRIPTION
-In addition to the global table described in
-.Xr ENGINE_add 3 ,
-the crypto library maintains several tables containing references to
-.Vt ENGINE
-objects implementing one specific cryptographic algorithm.
-.Pp
-The functions listed in the present manual page append

-to the end of the table for the respective algorithm.
-.Pp
-If
-.Fa e
-does not contain a method for the requested algorithm,
-these functions succeed without having any effect.
-.Pp
-If
-.Fa e
-is already registered for the given algorithm,
-they move it to the end of the respective table.
-.Pp
-.Fn ENGINE_register_ciphers
-and
-.Fn ENGINE_register_digests
-are special in so far as an engine may implement
-more than one cipher or more than one digest.
-In that case,
-.Fa e
-is registered for all the ciphers or digests it implements.
-.Pp
-.Fn ENGINE_register_complete
-registers
-.Fa e
-for all algorithms it implements by calling all the other functions.

-.Sh DESCRIPTION
-The
-.Fn ENGINE_set_*
-functions install a table of function pointers
-implementing the respective algorithm in
-.Fa e .
-Partial information about the various method objects is available from
-.Xr RSA_meth_new 3 ,
-.Xr RSA_get_default_method 3 ,
-.Xr DSA_meth_new 3 ,
-.Xr DSA_get_default_method 3 ,
-.Xr EC_KEY_get_default_method 3 ,
-.Xr DH_get_default_method 3 ,
-.Xr RAND_get_rand_method 3 ,
-.Xr EVP_get_cipherbynid 3 ,
-and
-.Xr EVP_get_digestbynid 3 .
-.Vt STORE_METHOD
-is an incomplete type, and the pointers to it are not used for anything.
-For complete descriptions of these types,
-refer to the respective header files.
-.Pp
-The functions described in the
-.Xr ENGINE_register_RSA 3
-and
-.Xr ENGINE_set_default 3
-manual pages only have an effect after function pointers
-were installed using the functions described here.
-.Pp
-.Fn ENGINE_set_ciphers
-and
-.Fn ENGINE_set_digests
-are special in so far as the
-.Vt ENGINE
-structure does not provide fields to store function pointers
-implementing ciphers or digests.
-Instead, these two functions only install a callback to
-retrieve implementations.
-Where the pointers to the implementations are stored internally,
-how they get initialized, and how the
-.Vt ENGINE_CIPHERS_PTR
-and
-.Vt ENGINE_DIGESTS_PTR
-callbacks retrieve them
-is up to the implementation of each individual engine.
-.Pp
-If the
-.Vt ENGINE_CIPHERS_PTR
-and
-.Vt ENGINE_DIGESTS_PTR
-callbacks are called with a non-zero
-.Fa nid ,
-they retrieve the implementation of that cipher or digest,
-respectively.
-In this case, a
-.Dv NULL
-pointer can be passed as the
-.Fa nids
-argument.
-.Fn ENGINE_get_cipher
-and
-.Fn ENGINE_get_digest
-call the callbacks installed in
-.Fa e
-in this way.
-.Pp
-If 0 is passed as the
-.Fa nid
-argument, an internal pointer
-to the array of implementations available in
-.Fa e
-is returned in
-.Pf * Fa impl ,
-and an internal pointer
-to the array of corresponding identifiers in
-.Pf * Fa nids .
-The return value of the callback indicates
-the number of implementations returned.
-.Pp
-The
-.Fn ENGINE_get_*
-functions retrieve the previously installed function tables.
-They are used when constructing basic cryptographic objects
-as shown in the following table:
-.Bl -column "ENGINE_get_digestMM"
-.It Accessor: Ta Called by:

-.Sh RETURN VALUES
-The
-.Fn ENGINE_set_*

-if none is installed.
-.Pp

-.Sh DESCRIPTION
-These functions register
-.Fa e
-as implementing the respective algorithm
-like the functions described in the
-.Xr ENGINE_register_RSA 3
-manual page do it.
-In addition, they call
-.Xr ENGINE_init 3
-on
-.Fa e
-and select
-.Fa e
-as the default implementation of the respective algorithm to be
-returned by the functions described in
-.Xr ENGINE_get_default_RSA 3
-in the future.
-If another engine was previously selected
-as the default implementation of the respective algorithm,
-.Xr ENGINE_finish 3
-is called on that previous engine.
-.Pp
-If
-.Fa e
-implements more than one cipher or digest,
-.Fn ENGINE_set_default_ciphers
-and
-.Fn ENGINE_set_default_digests
-register and select it for all these ciphers and digests, respectively.
-.Pp
-.Fn ENGINE_set_default
-registers
-.Fa e
-as the default implementation of all algorithms specified by the
-.Fa flags
-by calling the appropriate ones among the other functions.
-Algorithms can be selected by combining any number of the
-following constants with bitwise OR:
-.Dv ENGINE_METHOD_ALL ,
-.Dv ENGINE_METHOD_RSA ,
-.Dv ENGINE_METHOD_DSA ,
-.Dv ENGINE_METHOD_ECDH ,
-.Dv ENGINE_METHOD_ECDSA ,
-.Dv ENGINE_METHOD_DH ,
-.Dv ENGINE_METHOD_RAND ,
-.Dv ENGINE_METHOD_CIPHERS ,
-.Dv ENGINE_METHOD_DIGESTS ,
-.Dv ENGINE_METHOD_PKEY_METHS ,
-and
-.Dv ENGINE_METHOD_PKEY_ASN1_METHS .
-.Pp
-.Fn ENGINE_set_default_string
-is similar except that it selects the algorithms according to the string
-.Fa def_list ,
-which contains an arbitrary number of comma-separated keywords from
-the following list: ALL, RSA, DSA, ECDH, ECDSA, DH, RAND, CIPHERS,
-DIGESTS, PKEY_CRYPTO, PKEY_ASN1, and PKEY.
-PKEY_CRYPTO corresponds to
-.Dv ENGINE_METHOD_PKEY_METHS ,
-PKEY_ASN1 to
-.Dv ENGINE_METHOD_PKEY_ASN1_METHS ,
-and PKEY selects both.
-.Sh RETURN VALUES
-These functions return 1 on success or 0 on error.
-They fail if
-.Xr ENGINE_init 3
-fails or if insufficient memory is available.

-.Sh CAVEATS
-Failure of
-.Xr ENGINE_finish 3
-is ignored.
-.Sh BUGS
-Even when

-or

-fail, they typically still register
-.Fa e
-for some algorithms, but usually not for all it could be registered
-for by calling the individual functions.
