EVP_PKEY_cmp(3) 						      OpenSSL							   EVP_PKEY_cmp(3)

NAME
EVP_PKEY_copy_parameters, EVP_PKEY_missing_parameters, EVP_PKEY_cmp_parameters, EVP_PKEY_cmp - public key parameter and comparison functions SYNOPSIS
#include <openssl/evp.h> int EVP_PKEY_missing_parameters(const EVP_PKEY *pkey); int EVP_PKEY_copy_parameters(EVP_PKEY *to, const EVP_PKEY *from); int EVP_PKEY_cmp_parameters(const EVP_PKEY *a, const EVP_PKEY *b); int EVP_PKEY_cmp(const EVP_PKEY *a, const EVP_PKEY *b); DESCRIPTION
The function EVP_PKEY_missing_parameters() returns 1 if the public key parameters of pkey are missing and 0 if they are present or the algorithm doesn't use parameters. The function EVP_PKEY_copy_parameters() copies the parameters from key from to key to. The funcion EVP_PKEY_cmp_parameters() compares the parameters of keys a and b. The funcion EVP_PKEY_cmp() compares the public key components and paramters (if present) of keys a and b. NOTES
The main purpose of the functions EVP_PKEY_missing_parameters() and EVP_PKEY_copy_parameters() is to handle public keys in certificates where the parameters are sometimes omitted from a public key if they are inherited from the CA that signed it. Since OpenSSL private keys contain public key components too the function EVP_PKEY_cmp() can also be used to determine if a private key matches a public key. RETURN VALUES
The function EVP_PKEY_missing_parameters() returns 1 if the public key parameters of pkey are missing and 0 if they are present or the algorithm doesn't use parameters. These functions EVP_PKEY_copy_parameters() returns 1 for success and 0 for failure. The function EVP_PKEY_cmp_parameters() and EVP_PKEY_cmp() return 1 if the keys match, 0 if they don't match, -1 if the key types are different and -2 if the operation is not supported. SEE ALSO
