使用openssl命令行加密字符串 [英] Encrypt a string using openssl command line

问题描述

我有一个16字节的字符，我想使用openssl加密成16字节的加密字符串.

I have a 16 byte character that I would like to encrypt using openssl into a 16 byte encrypted string.

然后需要将此加密的字符串(人类可读格式)提供给使用它的用户，然后将该字符串解密为原始的16字节格式以进行比较和认证.任何人都可以告诉我，使用openssl命令行怎么可能.

This encrypted string ( in human readable format ) then needs to be supplied to a user who would use it, and the string would be decrypted to its original 16-byte form for comparison and authentication. Could anyone please tell me how this would be possible with openssl commandline.

先谢谢了.

推荐答案

这是在命令行上使用openssl加密字符串的一种方法(必须输入两次密码):

Here's one way to encrypt a string with openssl on the command line (must enter password twice):

echo -n "aaaabbbbccccdddd" | openssl enc -e -aes-256-cbc -a -salt
enter aes-256-cbc encryption password:
Verifying - enter aes-256-cbc encryption password:

输出内容如下:

U2FsdGVkX1/6LATntslD80T2HEIn3A0BqxarNfwbg31D2kI00dYbmBo8Mqt42PIm

据我所知，您无法控制输出的字节数.您可以对其进行b64或十六进制编码，仅此而已.另外，如果要将该字符串保存到文件而不是stdout中，请使用-out选项.

To my knowledge, you can't control the number of bytes out. You can b64 or hex encode it, but that's about it. Also, if you want to save that string to a file rather than stdout, use the -out option.
