Rsa签名算法

Rsa SHA256:

//Rsa SHA256
     $priKey = file_get_contents(__DIR__.'/file.pem');
     $privKeyId = openssl_pkey_get_private($priKey);
     $signature = '';
     $algo = "SHA256";
     openssl_sign($data, $signature, $privKeyId, $algo);
     openssl_free_key($privKeyId);
     $bs =  base64_encode($signature);
