-.Sh DESCRIPTION
-.Fn EVP_add_cipher
-adds
-.Fa cipher
-to a global lookup table so that it can be retrieved with
-.Xr EVP_get_cipherbyname 3
-using both its long and short names,
-as determined by the
-.Fa cipher Ns 's
-NID via
-.Xr OBJ_nid2ln 3
-and
-.Xr OBJ_nid2sn 3 .
-It is the caller's responsibility to ensure that the long
-and short names are not
-.Dv NULL .
-Internally, the lookup table is the global associative array and
-.Xr OBJ_NAME_add 3
-is used to add two key-value pairs with value pointer
-.Fa cipher
-and the keys consisting of the names and
-the type
-.Dv OBJ_NAME_TYPE_CIPHER_METH .
-.Pp
-.Fn EVP_add_cipher_alias
-and
-.Fn EVP_delete_cipher_alias
-add and remove the
-.Fa alias
-for the cipher
-.Fa name .
-They are implemented as macros wrapping
-.Xr OBJ_NAME_add 3
-and
-.Xr OBJ_NAME_remove 3
-with
-.Fa type
-set to the bitwise or of
-.Dv OBJ_NAME_TYPE_CIPHER_METH
-and
-.Dv OBJ_NAME_ALIAS .
-.Pp
-.Fn EVP_add_digest
-adds
-.Fa md
-to a global lookup table so that it can be retrieved with
-.Xr EVP_get_digestbyname 3
-using both its long and short names,
-as determined by the
-.Fa md Ns 's
-NID via
-.Xr OBJ_nid2ln 3
-and
-.Xr OBJ_nid2sn 3 .
-If the
-.Fa md
-has an associated public key signing algorithm (see
-.Xr EVP_MD_pkey_type 3 )
-distinct from the
-.Fa md ,
-the signing algorithm's short and long names are added as aliases for
-the short name of
-.Fa md .
-It is the caller's responsibility to ensure that all long
-and short names are not
-.Dv NULL .
-Internally, the lookup table is the global associative array and
-.Xr OBJ_NAME_add 3
-is used to add two key-value pairs with value pointer
-.Fa md
-and the keys consisting of the names and
-the type
-.Dv OBJ_NAME_TYPE_MD_METH .
-The aliases are added with
-.Fn EVP_add_digest_alias .
-.Pp
-.Fn EVP_add_digest_alias
-and
-.Fn EVP_delete_digest_alias
-add and remove the
-.Fa alias
-for the digest
-.Fa name .
-They are implemented as macros wrapping
-.Xr OBJ_NAME_add 3
-and
-.Xr OBJ_NAME_remove 3
-with
-.Fa type
-set to the bitwise or of
-.Dv OBJ_NAME_TYPE_MD_METH
-and
-.Dv OBJ_NAME_ALIAS .
-.Sh RETURN VALUES
-.Fn EVP_add_cipher ,
-.Fn EVP_add_cipher_alias ,
-.Fn EVP_add_digest ,
-and
-.Fn EVP_add_digest_alias
-return 1 on success or 0 if memory allocation fails.
-.Pp
-.Fn EVP_delete_cipher_alias
-and
-.Fn EVP_delete_digest_alias
-return 1 if one alias was removed or 0 otherwise.

-.Sh HISTORY
-.Fn EVP_add_cipher
-and
-.Fn EVP_add_digest
-first appeared in OpenSSL 0.9.0 and have been available since
-.Ox 2.4 .

-.Fn EVP_add_cipher_alias ,
-.Fn EVP_delete_cipher_alias ,
-.Fn EVP_add_digest_alias ,
-and
-.Fn EVP_delete_digest_alias
-first appeared in OpenSSL 0.9.4 and have been available since
-.Ox 2.6 .
-.Sh BUGS
-Key-value pairs already added before an error occurred
-remain in the global associative array,
-leaving it in an unknown state.
-.Pp
-While aliases can be added and removed, there is no dedicated API
-to remove added ciphers or digests.
