EVP_PKEY_new(3) 						      OpenSSL							   EVP_PKEY_new(3)

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 algo- rithm. 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. SEE ALSO

EVP_PKEY_set1_RSA, EVP_PKEY_set1_DSA, EVP_PKEY_set1_DH, EVP_PKEY_set1_EC_KEY, EVP_PKEY_get1_RSA, EVP_PKEY_get1_DSA, EVP_PKEY_get1_DH, EVP_PKEY_get1_EC_KEY, EVP_PKEY_assign_RSA, EVP_PKEY_assign_DSA, EVP_PKEY_assign_DH, EVP_PKEY_assign_EC_KEY, EVP_PKEY_type - EVP_PKEY 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_set1_DH(EVP_PKEY *pkey,DH *key); int EVP_PKEY_set1_EC_KEY(EVP_PKEY *pkey,EC_KEY *key); RSA *EVP_PKEY_get1_RSA(EVP_PKEY *pkey); DSA *EVP_PKEY_get1_DSA(EVP_PKEY *pkey); DH *EVP_PKEY_get1_DH(EVP_PKEY *pkey); EC_KEY *EVP_PKEY_get1_EC_KEY(EVP_PKEY *pkey); int EVP_PKEY_assign_RSA(EVP_PKEY *pkey,RSA *key); int EVP_PKEY_assign_DSA(EVP_PKEY *pkey,DSA *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. SEE ALSO
