-=head1 DESCRIPTION
-
-All of the functions described on this page are deprecated.
-Applications should instead use the OSSL_PROVIDER APIs.
-
-B<EVP_PKEY_METHOD> is a structure which holds a set of methods for a
-specific public key cryptographic algorithm. Those methods are usually
-used to perform different jobs, such as generating a key, signing or
-verifying, encrypting or decrypting, etc.
-
-There are two places where the B<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 by using L<EVP_PKEY_meth_add0(3)>.
-
-The B<EVP_PKEY_METHOD> objects are usually referenced by B<EVP_PKEY_CTX>
-objects.
-
-=head2 Methods
-
-The methods are the underlying implementations of a particular public key
-algorithm present by the B<EVP_PKEY_CTX> object.
-
- int (*init) (EVP_PKEY_CTX *ctx);
- int (*copy) (EVP_PKEY_CTX *dst, const EVP_PKEY_CTX *src);
- void (*cleanup) (EVP_PKEY_CTX *ctx);
-
-The init() method is called to initialize algorithm-specific data when a new
-B<EVP_PKEY_CTX> is created. As opposed to init(), the cleanup() method is called
-when an B<EVP_PKEY_CTX> is freed. The copy() method is called when an B<EVP_PKEY_CTX>
-is being duplicated. Refer to L<EVP_PKEY_CTX_new(3)>, L<EVP_PKEY_CTX_new_id(3)>,
-L<EVP_PKEY_CTX_free(3)> and L<EVP_PKEY_CTX_dup(3)>.
-
- int (*paramgen_init) (EVP_PKEY_CTX *ctx);
- int (*paramgen) (EVP_PKEY_CTX *ctx, EVP_PKEY *pkey);
-
-The paramgen_init() and paramgen() methods deal with key parameter generation.
-They are called by L<EVP_PKEY_paramgen_init(3)> and L<EVP_PKEY_paramgen(3)> to

- unsigned char *rout, size_t *routlen,
- const unsigned char *sig, size_t siglen);
-
-The verify_recover_init() and verify_recover() methods are used to verify a
-signature and then recover the digest from the signature (for instance, a
-signature that was generated by RSA signing algorithm). They are called by
-L<EVP_PKEY_verify_recover_init(3)> and L<EVP_PKEY_verify_recover(3)>.
-
- int (*signctx_init) (EVP_PKEY_CTX *ctx, EVP_MD_CTX *mctx);

-a B<EVP_MD_CTX> object. They are called by the EVP_DigestSign functions. See
-L<EVP_DigestSignInit(3)> for details.
-
- int (*verifyctx_init) (EVP_PKEY_CTX *ctx, EVP_MD_CTX *mctx);
- int (*verifyctx) (EVP_PKEY_CTX *ctx, const unsigned char *sig, int siglen,

-
- int (*decrypt_init) (EVP_PKEY_CTX *ctx);
- int (*decrypt) (EVP_PKEY_CTX *ctx, unsigned char *out, size_t *outlen,

-
- int (*derive_init) (EVP_PKEY_CTX *ctx);

-from a public key algorithm (for instance, the DH algorithm). They are called by
-L<EVP_PKEY_derive_init(3)> and L<EVP_PKEY_derive(3)>.
-
- int (*ctrl) (EVP_PKEY_CTX *ctx, int type, int p1, void *p2);
- int (*ctrl_str) (EVP_PKEY_CTX *ctx, const char *type, const char *value);
-
-The ctrl() and ctrl_str() methods are used to adjust algorithm-specific
-settings. See L<EVP_PKEY_CTX_ctrl(3)> and related functions for details.
-
- int (*digestsign) (EVP_MD_CTX *ctx, unsigned char *sig, size_t *siglen,
- const unsigned char *tbs, size_t tbslen);
- int (*digestverify) (EVP_MD_CTX *ctx, const unsigned char *sig,
- size_t siglen, const unsigned char *tbs,
- size_t tbslen);
-
-The digestsign() and digestverify() methods are used to generate or verify
-a signature in a one-shot mode. They could be called by L<EVP_DigestSign(3)>
-and L<EVP_DigestVerify(3)>.
-
- int (*check) (EVP_PKEY *pkey);
- int (*public_check) (EVP_PKEY *pkey);
- int (*param_check) (EVP_PKEY *pkey);
-
-The check(), public_check() and param_check() methods are used to validate a
-key-pair, the public component and parameters respectively for a given B<pkey>.
-They could be called by L<EVP_PKEY_check(3)>, L<EVP_PKEY_public_check(3)> and
-L<EVP_PKEY_param_check(3)> respectively.
-
- int (*digest_custom) (EVP_PKEY_CTX *ctx, EVP_MD_CTX *mctx);
-
-The digest_custom() method is used to generate customized digest content before
-the real message is passed to functions like L<EVP_DigestSignUpdate(3)> or
-L<EVP_DigestVerifyInit(3)>. This is usually required by some public key
-signature algorithms like SM2 which requires a hashed prefix to the message to
-be signed. The digest_custom() function will be called by L<EVP_DigestSignInit(3)>
-and L<EVP_DigestVerifyInit(3)>.
-
-=head2 Functions
-
-EVP_PKEY_meth_new() creates and returns a new B<EVP_PKEY_METHOD> object,
-and associates the given B<id> and B<flags>. The following flags are
-supported:
-
- EVP_PKEY_FLAG_AUTOARGLEN
- EVP_PKEY_FLAG_SIGCTX_CUSTOM
-
-If an B<EVP_PKEY_METHOD> is set with the B<EVP_PKEY_FLAG_AUTOARGLEN> flag, the
-maximum size of the output buffer will be automatically calculated or checked
-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
-L<EVP_PKEY_sign(3)>.
-
-The B<EVP_PKEY_FLAG_SIGCTX_CUSTOM> is used to indicate the signctx() method
-of an B<EVP_PKEY_METHOD> is always called by the EVP framework while doing a
-digest signing operation by calling L<EVP_DigestSignFinal(3)>.
-
-EVP_PKEY_meth_free() frees an existing B<EVP_PKEY_METHOD> pointed by
-B<pmeth>. If the argument is NULL, nothing is done.
-
-EVP_PKEY_meth_copy() copies an B<EVP_PKEY_METHOD> object from B<src>
-to B<dst>.
-
-EVP_PKEY_meth_find() finds an B<EVP_PKEY_METHOD> object with the B<id>.
-This function first searches through the user-defined method objects and
-then the built-in objects.
-
-EVP_PKEY_meth_add0() adds B<pmeth> to the user defined stack of methods.
-
-EVP_PKEY_meth_remove() removes an B<EVP_PKEY_METHOD> object added by
-EVP_PKEY_meth_add0().
-
-The EVP_PKEY_meth_set functions set the corresponding fields of
-B<EVP_PKEY_METHOD> structure with the arguments passed.
-
-The EVP_PKEY_meth_get functions get the corresponding fields of
-B<EVP_PKEY_METHOD> structure to the arguments provided.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_meth_new() returns a pointer to a new B<EVP_PKEY_METHOD>
-object or returns NULL on error.
-
-EVP_PKEY_meth_free() and EVP_PKEY_meth_copy() do not return values.
-
-EVP_PKEY_meth_find() returns a pointer to the found B<EVP_PKEY_METHOD>
-object or returns NULL if not found.
-
-EVP_PKEY_meth_add0() returns 1 if method is added successfully or 0
-if an error occurred.
-
-EVP_PKEY_meth_remove() returns 1 if method is removed successfully or
-0 if an error occurred.
-
-All EVP_PKEY_meth_set and EVP_PKEY_meth_get functions have no return
-values. For the 'get' functions, function pointers are returned by
-arguments.
-
-=head1 HISTORY
-
-All of these functions were deprecated in OpenSSL 3.0.
-
-The signature of the I<copy> functional argument of EVP_PKEY_meth_set_copy()
-has changed in OpenSSL 3.0 so its I<src> parameter is now constified.
