signature= encrypt(privateKey, sha256(message)) 对签名进行验证实际上就是用公钥解密: hash= decrypt(publicKey, signature) 然后把解密后的哈希与原始消息的哈希进行对比。 因为用户总是使用自己的私钥进行签名,所以,私钥就相当于用户身份。而公钥用来给外部验证用户身份。 常用数字签名算法有: MD5withRSA SHA1wit...

php解决方案比java端更“简单”，可以使用key和salt作为直接输入（无需转换它们）。当您想比较base64编码的密文时，示例代码返回base64编码的密文，而不是java程序发出的十六进制字符串。这是具有相同结果的输出：
