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.
