EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH(), and EVP_PKEY_set1_EC_KEY() set the key referenced by pkey to key and increment the reference count of key by 1 in case of success. EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH(), and EVP_PKEY_get1_EC_KEY() return the key referenced in pkey, incrementing its reference count by 1, or NULL if the key is not of the correct type. EVP_PKEY_get0_RSA(), EVP_PKEY_get0_DSA(), EVP_PKEY_get0_DH(), EVP_PKEY_get0_EC_KEY(), and EVP_PKEY_get0() are identical except that they do not increment the reference count. Consequently, the returned key must not be freed by the caller. EVP_PKEY_get0_hmac() returns an internal pointer to the key referenced in pkey and sets *len to its length in bytes. The returned pointer must not be freed by the caller. If pkey is not of the correct type, NULL is returned and the content of *len becomes unspecified. EVP_PKEY_assign_RSA(), EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH(), EVP_PKEY_assign_EC_KEY(), EVP_PKEY_assign_GOST(), and EVP_PKEY_assign() also set the referenced key to key; however these use the supplied key internally without incrementing its reference count, such that key will be freed when the parent pkey is freed. If the key is of the wrong type, these functions report success even though pkey ends up in a corrupted state. Even the functions explicitly containing the type in their name are not type safe because they are implemented as macros. The following types are supported: EVP_PKEY_RSA, EVP_PKEY_DSA, EVP_PKEY_DH, EVP_PKEY_EC, and EVP_PKEY_GOSTR01. EVP_PKEY_base_id() returns the type of pkey according to the following table: return value PEM type string EVP_PKEY_CMAC = NID_cmac CMAC EVP_PKEY_DH = NID_dhKeyAgreement DH EVP_PKEY_DSA = NID_dsa DSA EVP_PKEY_EC = NID_X9_62_id_ecPublicKey EC EVP_PKEY_GOSTIMIT = NID_id_Gost28147_89_MAC GOST-MAC EVP_PKEY_GOSTR01 = NID_id_GostR3410_2001 GOST2001 EVP_PKEY_HMAC = NID_hmac HMAC EVP_PKEY_RSA = NID_rsaEncryption RSA EVP_PKEY_RSA_PSS = NID_rsassaPss RSA-PSS Application programs can support additional key types by calling EVP_PKEY_asn1_add0(3). EVP_PKEY_id() returns the actual OID associated with pkey. Historically keys using the same algorithm could use different OIDs. The following deprecated aliases are still supported: return value alias for EVP_PKEY_DSA1 = NID_dsa_2 DSA EVP_PKEY_DSA2 = NID_dsaWithSHA DSA EVP_PKEY_DSA3 = NID_dsaWithSHA1 DSA EVP_PKEY_DSA4 = NID_dsaWithSHA1_2 DSA EVP_PKEY_GOSTR12_256 = NID_id_tc26_gost3410_2012_256 GOST2001 EVP_PKEY_GOSTR12_512 = NID_id_tc26_gost3410_2012_512 GOST2001 EVP_PKEY_RSA2 = NID_rsa RSA Application programs can support additional alternative OIDs by calling EVP_PKEY_asn1_add_alias(3). Most applications wishing to know a key type will simply call EVP_PKEY_base_id() and will not care about the actual type, which will be identical in almost all cases. EVP_PKEY_type() returns the underlying type of the NID type. For example, EVP_PKEY_type(EVP_PKEY_RSA2) will return EVP_PKEY_RSA. EVP_PKEY_set_type() frees the key referenced in pkey, if any, and sets the key type of pkey to type without referencing a new key from pkey yet. For type, any of the possible return values of EVP_PKEY_base_id() and EVP_PKEY_id() can be passed. In accordance with the OpenSSL naming convention, the key obtained from or assigned to pkey using the 1 functions must be freed as well as pkey.


EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH(), EVP_PKEY_set1_EC_KEY(), EVP_PKEY_assign_RSA(), EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH(), EVP_PKEY_assign_EC_KEY(), EVP_PKEY_assign_GOST(), EVP_PKEY_assign(), and EVP_PKEY_set_type() return 1 for success or 0 for failure. EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH(), EVP_PKEY_get1_EC_KEY(), EVP_PKEY_get0_RSA(), EVP_PKEY_get0_DSA(), EVP_PKEY_get0_DH(), EVP_PKEY_get0_EC_KEY(), EVP_PKEY_get0_hmac(), and EVP_PKEY_get0() return the referenced key or NULL if an error occurred. For EVP_PKEY_get0(), the return value points to an RSA, DSA, DH, EC_KEY, GOST_KEY, or ASN1_OCTET_STRING object depending on the type of pkey. EVP_PKEY_base_id(), EVP_PKEY_id(), and EVP_PKEY_type() return a key type or NID_undef (equivalently EVP_PKEY_NONE) on error.
