前言

secret_id: 密钥的Id

secret_key: 密钥的Key

SHA1: 签名方式

hash_hmac: php hash函数

hash_hmac_file:生成密钥

1.生成secret_key

hash_hmac_file('SHA1','signature.txt','secret');

2.生成签名

base64_encode(hash_hmac('SHA1', $init, $secret_key, true).$init);

3.签名比对

base64_decode($initSign);

base64_encode(hash_hmac('SHA1', $init, $secret_key, true).$init);

4.网站验证(sha1.html)

访问 sha1.html

5.代码
