+.Sh DESCRIPTION
+The
+.Vt EVP_PKEY_METHOD
+structure holds a set of methods
+for a specific public key cryptographic algorithm.
+Those methods perform tasks such as generating keys, signing, verifying,
+encrypting, decrypting, and so on.
+.Pp
+There are two places where the
+.Vt EVP_PKEY_METHOD
+objects are stored: one is a built-in static array representing the
+standard methods for different algorithms, and the other one is a stack
+of user-defined application-specific methods, which can be manipulated
+with
+.Fn EVP_PKEY_meth_add0 .
+.Pp
+The
+.Vt EVP_PKEY_METHOD
+objects are usually referenced by
+.Vt EVP_PKEY_CTX
+objects.
+.Ss Methods
+The methods implement the particular public key algorithm represented by the
+.Vt EVP_PKEY_CTX
+object.

+The

+.Xr EVP_PKEY_CTX_new 3
+and
+.Xr EVP_PKEY_CTX_new_id 3
+to initialize the algorithm-specific data when a new
+.Vt EVP_PKEY_CTX
+is created.
+The
+.Fn cleanup
+method is called by
+.Xr EVP_PKEY_CTX_free 3
+when an
+.Vt EVP_PKEY_CTX
+is freed.
+The
+.Fn copy
+method is called by

+.Vt EVP_PKEY_CTX
+is duplicated.

+object with the given
+.Fa id
+and
+.Fa flags .
+The following flags are supported:
+.Bl -tag -width Ds
+.It Dv EVP_PKEY_FLAG_AUTOARGLEN
+Automatically calculate the maximum size of the output buffer
+in corresponding EVP methods by the EVP framework.
+Thus the implementations of these methods don't need to care about
+handling the case of returning output buffer size by themselves.
+For details on the output buffer size, refer to
+.Xr EVP_PKEY_sign 3 .
+.It Dv EVP_PKEY_FLAG_SIGCTX_CUSTOM
+Indicate that the
+.Fn signctx
+method of an
+.Vt EVP_PKEY_METHOD
+is always called by the EVP framework while doing a digest signing
+operation by calling
+.Xr EVP_DigestSignFinal 3 .
+.El
+.Pp
+.Fn EVP_PKEY_meth_free
+frees
+.Fa pmeth .
+.Pp
+.Fn EVP_PKEY_meth_copy
+copies
+.Fa src
+to
+.Fa dst .
+.Pp
+.Fn EVP_PKEY_meth_find
+finds an
+.Vt EVP_PKEY_METHOD
+object with the given
+.Fa id .
+This function first searches through the user-defined method objects and
+then through the built-in objects.
+.Pp
+.Fn EVP_PKEY_meth_add0
+adds
+.Fa pmeth
+to the stack of user defined methods.
+.Pp
+The
+.Fn EVP_PKEY_meth_set_*
+functions set the corresponding fields of
+.Fa pmeth
+to the arguments passed.
+.Sh RETURN VALUES
+.Fn EVP_PKEY_meth_new
+returns a pointer to a new
+.Vt EVP_PKEY_METHOD
+object or
+.Dv NULL
+on error.
+.Pp
+.Fn EVP_PKEY_meth_find
+returns a pointer to the found
+.Vt EVP_PKEY_METHOD
+object or
+.Dv NULL
+if no matching object is found.
+.Pp
+.Fn EVP_PKEY_meth_add0
+returns 1 if the method is added successfully or 0 if an error occurred.
