For example an \s-1RSA\s0 key will return \fB\s-1EVP_PKEY_RSA\s0\fR. .PP \&\fBEVP_PKEY_id()\fR returns the actual \s-1OID\s0 associated with \fBpkey\fR. Historically keys using the same algorithm could use different OIDs. For example an \s-1RSA\s0 key could use the OIDs corresponding to the NIDs \fBNID_rsaEncryption\fR (equivalent to \&\fB\s-1EVP_PKEY_RSA\s0\fR) or \fBNID_rsa\fR (equivalent to \fB\s-1EVP_PKEY_RSA2\s0\fR). The use of alternative non-standard OIDs is now rare so \fB\s-1EVP_PKEY_RSA2\s0\fR et al are not often seen in practice. .PP \&\fBEVP_PKEY_type()\fR returns the underlying type of the \s-1NID\s0 \fBtype\fR. For example EVP_PKEY_type(\s-1EVP_PKEY_RSA2\s0) will return \fB\s-1EVP_PKEY_RSA\s0\fR. .PP \&\fBEVP_PKEY_get0_engine()\fR returns a reference to the \s-1ENGINE\s0 handling \fBpkey\fR. .PP \&\fBEVP_PKEY_set1_engine()\fR sets the \s-1ENGINE\s0 handling \fBpkey\fR to \fBengine\fR. It must be called after the key algorithm and components are set up. If \fBengine\fR does not include an \fB\s-1EVP_PKEY_METHOD\s0\fR for \fBpkey\fR an error occurs. .PP \&\fBEVP_PKEY_set_alias_type()\fR allows modifying a \s-1EVP_PKEY\s0 to use a different set of algorithms than the default. This is currently used to support \s-1SM2\s0 keys, which use an identical encoding to \s-1ECDSA.\s0 .SH "NOTES" .IX Header "NOTES" In accordance with the OpenSSL naming convention the key obtained from or assigned to the \fBpkey\fR using the \fB1\fR functions must be freed as well as \fBpkey\fR. .PP \&\fBEVP_PKEY_assign_RSA()\fR, \fBEVP_PKEY_assign_DSA()\fR, \fBEVP_PKEY_assign_DH()\fR, \&\fBEVP_PKEY_assign_EC_KEY()\fR, \fBEVP_PKEY_assign_POLY1305()\fR and \fBEVP_PKEY_assign_SIPHASH()\fR are implemented as macros. .PP Most applications wishing to know a key type will simply call \&\fBEVP_PKEY_base_id()\fR and will not care about the actual type: which will be identical in almost all cases. .PP Previous versions of this document suggested using EVP_PKEY_type(pkey\->type) to determine the type of a key. Since \fB\s-1EVP_PKEY\s0\fR is now opaque this is no longer possible: the equivalent is EVP_PKEY_base_id(pkey). .PP \&\fBEVP_PKEY_set1_engine()\fR is typically used by an \s-1ENGINE\s0 returning an \s-1HSM\s0 key as part of its routine to load a private key. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBEVP_PKEY_set1_RSA()\fR, \fBEVP_PKEY_set1_DSA()\fR, \fBEVP_PKEY_set1_DH()\fR and \&\fBEVP_PKEY_set1_EC_KEY()\fR return 1 for success or 0 for failure. .PP \&\fBEVP_PKEY_get1_RSA()\fR, \fBEVP_PKEY_get1_DSA()\fR, \fBEVP_PKEY_get1_DH()\fR and \&\fBEVP_PKEY_get1_EC_KEY()\fR return the referenced key or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBEVP_PKEY_assign_RSA()\fR, \fBEVP_PKEY_assign_DSA()\fR, \fBEVP_PKEY_assign_DH()\fR, \&\fBEVP_PKEY_assign_EC_KEY()\fR, \fBEVP_PKEY_assign_POLY1305()\fR and \fBEVP_PKEY_assign_SIPHASH()\fR return 1 for success and 0 for failure. .PP \&\fBEVP_PKEY_base_id()\fR, \fBEVP_PKEY_id()\fR and \fBEVP_PKEY_type()\fR return a key type or \fBNID_undef\fR (equivalently \fB\s-1EVP_PKEY_NONE\s0\fR) on error. .PP \&\fBEVP_PKEY_set1_engine()\fR returns 1 for success and 0 for failure. .PP \&\fBEVP_PKEY_set_alias_type()\fR returns 1 for success and 0 for error. .SH "EXAMPLES" .IX Header "EXAMPLES" After loading an \s-1ECC\s0 key, it is possible to convert it to using \s-1SM2\s0 algorithms with EVP_PKEY_set_alias_type: .PP .Vb 1 \& EVP_PKEY_set_alias_type(pkey, EVP_PKEY_SM2); .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBEVP_PKEY_new\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2002\-2019 The OpenSSL Project Authors.
