使用cryptojs的Java到JS和JS到Java的加密

Question

几周前,我在这篇文章中得到了完美的工作: 适用于Java和Javascript的兼容AES算法

现在,我需要进行相反的操作,但是在java中,我得到了这个异常:

javax.crypto.BadPaddingException: Given final block not properly padded
at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:966)
at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:824)
at com.sun.crypto.provider.AESCipher.engineDoFinal(AESCipher.java:436)
at javax.crypto.Cipher.doFinal(Cipher.java:2165)

这是我在JavaScript中执行的"反向"操作:

var rkEncryptionKey = CryptoJS.enc.Base64.parse('u/Gu5posvwDsXUnV5Zaq4g==');
var rkEncryptionIv = CryptoJS.enc.Base64.parse('5D9r9ZVzEYYgha93/aUK2w==');

function encryptString(stringToEncrypt) {
    var utf8Stringified = CryptoJS.enc.Utf8.parse(stringToEncrypt);
    var encrypted = CryptoJS.AES.encrypt(utf8Stringified.toString(), rkEncryptionKey, {mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7, iv: rkEncryptionIv});
    return CryptoJS.enc.Base64.parse(encrypted.toString()).toString();
}

我虽然这就是全部？

加密字符串如下: {"company_name":"asdfasdfasd","customer_name":"asdfasdfasdfasdf","phone_number":"asdfasdfasdfasdf","email":"asdfasdfasdfasdfads"}

当从java到java进行加密/解密时,它可以工作,当从java到javascript这样做时,也可以工作,但是从javascript到java,不能正常工作.

Java代码

public String toJson(final String encrypted) {
    try {
        SecretKey key = new SecretKeySpec(Base64.decodeBase64("u/Gu5posvwDsXUnV5Zaq4g=="), "AES");
        AlgorithmParameterSpec iv = new IvParameterSpec(Base64.decodeBase64("5D9r9ZVzEYYgha93/aUK2w=="));
        byte[] decodeBase64 = Base64.decodeBase64(encrypted);

        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE, key, iv);

        return new String(cipher.doFinal(decodeBase64), "UTF-8");
    } catch (Exception e) {
        throw new RuntimeException("This should not happen in production.", e);
    }
}

更改

return CryptoJS.enc.Base64.parse(encrypted.toString()).toString();

至

return encrypted.ciphertext.toString(CryptoJS.enc.Base64);

该encrypted对象通常会串行化为OpenSSL格式,该格式也可能包含salt.如果您只对实际的密文感兴趣,那么您需要对该ciphertext属性进行字符串化.

请注意,toString()它采用可选的编码功能.使用您需要的那个.
