console error #39;Illegal base64 character 20#39;(控制台错误#39；非法的Base64字符20#39；)

本文介绍了控制台错误&#39；非法的Base64字符20&#39；的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用以下代码进行加密和解密，而解密在运行时遇到错误。错误消息是‘非法的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);

SecretKey： 

 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();

如何才能不出错地解密加密值

加密值=3aW0qv4pN+y3Tj8raXDHtos95ChpLu2JzEnfW+KfgEE=

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

显示两个空格"+"转换为"(Space)"

现在我已将密钥更改为‘sa278asabmnbmnbm’

我以40SRNEe9PgaxEeprPyqlyeP08hBHq00Ow9WWBgP6ZTM=

的身份获取加密值

解密时，我得到[B@75141845作为解密值

推荐答案

我很清楚回答此问题已经晚了。但是，我偶然发现了一个非常相似的情况，我很乐意分享我的学习作为答案，而不是评论，因为它并不简短。 我将简要解释我的上下文&我是如何遇到这种情况的。我还记录了my learnings here as an answer的详细信息。 我一直在玩JASYPT加密，其中我使用了私钥。

String jasyptPrivateKey = "Hello@123";，其中包含'@'。 然而，有几件事我忽略了，这导致了我短暂的失败。

以下是我编写的Spock单元测试用例的堆栈跟踪。

Solution 我忘了将Bean名称添加到getJasyptStringEncryptor Bean中。

'@Bean(name = "jasyptStringEncryptor")' 这将注册Bean，并允许应用程序了解该Bean。此外，我还将@EnableEncryptableProperties添加到前面缺失的Configuration类中。

在my answer here中，如果您正在为加密而苦苦挣扎，或者可以为您提供很少的线索和您没有做过的其他可能的试用，您会发现许多其他详细信息。 我已尽力做到冗长而清晰&；希望这能帮助您并节省您的时间。
