几天以来，我试图弄清楚为什么我在 javascript(cryptojs) 和 java 中有不同的加密输出。我陷入了困境，不知道该改变什么，我想我会为此失去理智。这是完整的代码，应该很容易复制粘贴以进行测试。你是我最后的希望。 ^^
plainText = plaintext
password = password
salt = 3FF2EC019C627B945225DEBAD71A01B6985FE84C95A70EB132882F88C0A59A55
iv = 3C46C00F42A6044A"
Javascript result = zbohHpV5RtmHiH3cKDY15w==
Java result = wVdRQiIqkyVlttkWpCMSpQ==
Javascript html:更新并将迭代更改为 10

最佳答案
最后，感谢 pasimako 让我上路，他们都是平等的。我必须更改 iv 和 salt 转换为十六进制的方式以及 iv 的长度，并且如上所述，keySize 和 iterationCount 变量也未定义。
这是完整的工作代码。
它们都应该输出:
