EVP_PKEY_new(3) 						      OpenSSL							   EVP_PKEY_new(3)

NAME

       EVP_PKEY_new, EVP_PKEY_free - private key allocation functions.

SYNOPSIS

	#include <openssl/evp.h>

	EVP_PKEY *EVP_PKEY_new(void);
	void EVP_PKEY_free(EVP_PKEY *key);

DESCRIPTION

       The EVP_PKEY_new() function allocates an empty EVP_PKEY structure which is used by OpenSSL to store private keys.

       EVP_PKEY_free() frees up the private key key.

NOTES

       The EVP_PKEY structure is used by various OpenSSL functions which require a general private key without reference to any particular
       algorithm.

       The structure returned by EVP_PKEY_new() is empty. To add a private key to this empty structure the functions described in
       EVP_PKEY_set1_RSA(3) should be used.

RETURN VALUES

       EVP_PKEY_new() returns either the newly allocated EVP_PKEY structure of NULL if an error occurred.

       EVP_PKEY_free() does not return a value.

       assignment functions.

SYNOPSIS

	#include <openssl/evp.h>

	int EVP_PKEY_set1_RSA(EVP_PKEY *pkey,RSA *key);
	int EVP_PKEY_set1_DSA(EVP_PKEY *pkey,DSA *key);

	int EVP_PKEY_assign_RSA(EVP_PKEY *pkey,RSA *key);

	int EVP_PKEY_assign_DH(EVP_PKEY *pkey,DH *key);
	int EVP_PKEY_assign_EC_KEY(EVP_PKEY *pkey,EC_KEY *key);

	int EVP_PKEY_type(int type);

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.
