Question

我需要使用公钥使用PHP对消息进行编码，并使用私钥解析此消息。

这是测试代码：

var memberList = {member: [1, 2, 3, ...]}

但这不起作用。为什么呢？

Answer 1

CryptoJS解密需要CipherParams个对象代替密文，而WordArray代替密钥。如果您将密钥作为字符串传递，那么它将假定它是一个密码并尝试从MD5和不存在的盐中获取密钥。

尝试解析所有内容：

var decrypted = CryptoJS.RC4.decrypt({
    ciphertext: CryptoJS.enc.Base64.parse(encrypted)
}, CryptoJS.enc.Latin1.parse(theKey));

JSEncrypt返回＆＃34;普通字符串＆＃34;来自crypt.decrypt()函数，这意味着它必须用Latin1或UTF-8编码解析。
但我无法使用JSEncrypt，所以我使用了forge代替：

var privateKey = forge.pki.privateKeyFromPem(private_key);
var theKey = privateKey.decrypt(forge.util.decode64(envelope), 'RSAES-PKCS1-V1_5');

CrypoJS＆＃39; .toString()默认返回十六进制编码版本。您可以覆盖它以获取文本数据：

console.log(decrypted.toString(CryptoJS.enc.Utf8));
