为什么我的加密字符串看起来像只包含问号? [英] Why does my encrypted string looks like consisting of only question marks?
问题描述
我在使用Java加密字符串,当我打印加密的数据时,我只看到问号。
例如:
-
纯文字:
jjkkjlkljkj
-
加密文字:
- p>再次解密此文本后,我再次收到
jjkkjlkljkj
。
所以它看起来像加密工作正常。但是为什么我只能看到问号?
是的,因为你不能打印从加密。
请注意,将加密结果保存在字符串中可能会导致数据丢失 ,因此不要这样做。将其作为字节数组,并将其转换为可显示的格式,如 Base64 或只是简单的Hex 。
I'm encrypting a string in Java, and when I'm printing the encrypted data, I see only question marks.
As an example:
Plain text:
jjkkjlkljkj
Encrypted text:
???????????
After decrypting this text again, I'm getting
jjkkjlkljkj
again.
So it looks like the encryption worked right. But why can I see only question marks?
Yes, it's because you can't print the strings that are resulting from the encryption.
Note that saving the encrypted result in a string will possibly result in loss of the data, so don't do that. Take it as a byte array, and convert it to a displayable format, like Base64 or just simple Hex.
