# DESCRIPTION

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.

EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and EVP_PKEY_get1_EC_KEY() return the referenced key in pkey or NULL if the key is not of the correct type.

`EVP_PKEY_assign_RSA()` `EVP_PKEY_assign_DSA()`, `EVP_PKEY_assign_DH()` and `EVP_PKEY_assign_EC_KEY()` also set the referenced key to key however these use the supplied key internally and so key will be freed when the parent pkey is freed.

`EVP_PKEY_type()` returns the type of key corresponding to the value type. The type of a key can be obtained with EVP_PKEY_type(pkey->type). The return value will be EVP_PKEY_RSA, EVP_PKEY_DSA, EVP_PKEY_DH or EVP_PKEY_EC for the corresponding key types or NID_undef if the key type is unassigned.

# NOTES

In accordance with the OpenSSL naming convention the key obtained from or assigned to the pkey using the 1 functions must be freed as well as pkey.

`EVP_PKEY_assign_RSA()` `EVP_PKEY_assign_DSA()`, `EVP_PKEY_assign_DH()` `EVP_PKEY_assign_EC_KEY()` are implemented as macros.

# RETURN VALUES

EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH() and EVP_PKEY_set1_EC_KEY() return 1 for success or 0 for failure.

EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and EVP_PKEY_get1_EC_KEY() return the referenced key or NULL if an error occurred.

`EVP_PKEY_assign_RSA()` `EVP_PKEY_assign_DSA()`, `EVP_PKEY_assign_DH()` and `EVP_PKEY_assign_EC_KEY()` return 1 for success and 0 for failure.
