控制台错误“非法 base64 字符 20”

Question

我正在使用以下代码进行加密和解密，而解密时我在运行时遇到错误。 错误消息是“非法 base64 字符 20”

加密代码：

String secretValue = "sazhwsxplokmeroo";
keyValue = secretValue.getBytes();
Key generatedKey = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.ENCRYPT_MODE, generatedKey);
byte[] encValue = c.doFinal(userEmail.getBytes());
String encryptedValue = Base64.getEncoder().encodeToString(encValue);

密钥：

 private Key generateKey() {
     Key secretKey = new SecretKeySpec(keyValue, ALGO);
     return secretKey;
}

解密代码：

String secretValue = "sazhwsxplokmeroo";
keyValue = secretValue.getBytes();
Key generatedKey = generateKey();
Cipher c = Cipher.getInstance(ALGO);
c.init(Cipher.DECRYPT_MODE, generatedKey);
byte[] decodedValue = Base64.getDecoder().decode(encryptEmail.getBytes()); //error throws from this line as illegal base64 character 20
byte[] decValue = c.doFinal(decodedValue);
String decryptedValue = decValue.toString();

如何解密加密的值而不会出错

加密值 = 3aW0qv4pN+y3Tj8raXDHtos95ChpLu2JzEnfW+KfgEE=

此值在弹簧控制器中显示为 = 3aW0qv4pN y3Tj8raXDHtos95ChpLu2JzEnfW KfgEE=

它显示两个空格“+”被转换为“（空格）”

现在我已将我的密钥更改为“sa278asabmnbmnbm”

我将加密值设为 40SRNEe9PgaxEeprPyqlyeP08hBHq00Ow9WWBgP6ZTM=

解密时我得到 [B@75141845 作为解密值

我很清楚我回答这个问题迟了。 但是，我偶然发现了一个非常“相似”的情况，并且很高兴分享我的学习作为答案而不是评论，因为它并不短。 我将简要解释我的背景以及我是如何遇到这种情况的。 我也在这里记录了我的学习作为一个带有微小细节的答案。 我一直在玩 JASYPT 加密，我使用了私钥。

String jasyptPrivateKey = "Hello@123"; 其中包含'@' 。 然而，我忽略了一些导致我短暂失败的事情。

以下是我编写的 Spock 单元测试用例的堆栈跟踪。

Solution我忘记将 Bean 名称添加到我的 getJasyptStringEncryptor bean。

'@Bean(name = "jasyptStringEncryptor")'这注册了 bean 并允许应用程序知道这个 bean。 此外，我还将@EnableEncryptableProperties添加到我之前缺少的配置类中。

在我在这里的回答中，如果您在加密方面遇到困难，或者可以为您提供一些线索和其他您尚未完成的可能试验，您会发现许多其他详细信息。 我试图做到详细和清晰，希望它可以帮助并节省您的时间。
