php openssl(SHA1WithRSA) 签名 验签
签名:
public function wjSign($data){
$key = openssl_pkey_get_private(file_get_contents($this->privateKeyPathWJ));
openssl_sign($data, $sign, $key, OPENSSL_ALGO_SHA1);
$sign = base64_encode($sign);
return $sign;
}
验签:
public function wjVerify($data, $sign){
$sign = base64_decode($sign);
$key = openssl_pkey_get_public(file_get_contents($this->publicKeyPathWJ));
$result = openssl_verify($data, $sign, $key, OPENSSL_ALGO_SHA1) === 1;
return $result;
