signature=1be7575a614ba3597c2c53247a739d1c,错误openssl_sign(): supplied key param cannot be coerced in...

原因：RSA 的秘钥一般都有固定换行格式

私钥：

$str=’私钥(改成一行)’;

$str = chunk_split($str, 64, "\n");

$key = "-----BEGIN RSA PRIVATE KEY-----\n$str-----END RSA PRIVATE KEY-----\n";

$signature = '';

if (openssl_sign($data, $signature, $key, OPENSSL_ALGO_MD5)) {

echo base64_encode($signature);

}

公钥：

$data='内容';

$str='公钥(改成一行)';

$str = chunk_split($str, 64, "\n");

$key = "-----BEGIN PUBLIC KEY-----\n$str-----END PUBLIC KEY-----\n";

$signature = "";

if (openssl_verify(base64_decode($data), $signature, $key, OPENSSL_ALGO_MD5) == 1) {

echo $signature;

}

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;//1成功 0失败 -1错误

return $result;

}
