Question

我收到一个我无法解释的错误。

public static String encrypt(String plain, SaltPasswordPair saltPassword) {
    String password = saltPassword.getPassword();
    String salt = saltPassword.getSalt();

    TextEncryptor encryptor = Encryptors.text(password, salt);
    String encrypted = encryptor.encrypt(plain);

    return encrypted;
}

这是我的代码。无论密码长度（4,16，任何其他）或盐长度或我传递的任何值（我也尝试过1：1复制和粘贴来自此处的示例[Stackoverflow]和其他一些页面），我得到此异常：

我错过了什么吗？加密版本是4.2.2.RELEASE

编辑：有没有办法解决这个问题，而无需将外部JAR添加到我的JDK目录中？

Answer 1

private String cryptKey =＆＃34; qkjll5 @ 2md3gs5Q @ FDFqf＆＃34 ;;

默认情况下，Java仅支持128位加密（128位== 16Bytes == 16 Chars）

Removing the 128-bit key restriction in Java

Spring加密无效密钥大小
