1=pod 2 3=head1 NAME 4 5EVP_PKEY_new, EVP_PKEY_free - private key allocation functions. 6 7=head1 SYNOPSIS 8 9 #include <openssl/evp.h> 10 11 EVP_PKEY *EVP_PKEY_new(void); 12 void EVP_PKEY_free(EVP_PKEY *key); 13 14 15=head1 DESCRIPTION 16 17The EVP_PKEY_new() function allocates an empty B<EVP_PKEY> 18structure which is used by OpenSSL to store private keys. 19 20EVP_PKEY_free() frees up the private key B<key>. 21 22=head1 NOTES 23 24The B<EVP_PKEY> structure is used by various OpenSSL functions 25which require a general private key without reference to any 26particular algorithm. 27 28The structure returned by EVP_PKEY_new() is empty. To add a 29private key to this empty structure the functions described in 30L<EVP_PKEY_set1_RSA(3)|EVP_PKEY_set1_RSA(3)> should be used. 31 32=head1 RETURN VALUES 33 34EVP_PKEY_new() returns either the newly allocated B<EVP_PKEY> 35structure of B<NULL> if an error occurred. 36 37EVP_PKEY_free() does not return a value. 38 39=head1 SEE ALSO 40 41L<EVP_PKEY_set1_RSA(3)|EVP_PKEY_set1_RSA(3)> 42 43=head1 HISTORY 44 45TBA 46 47=cut 48
