OpenSSL in bash script
提问by alvatar
I'm trying to make a bash script in linux where some encrypted data is embedded and then retrieved and decrypted with openssl, like this:
我正在尝试在 linux 中制作一个 bash 脚本，其中嵌入了一些加密数据，然后使用 openssl 检索和解密，如下所示：
cat | openssl des3 -d -a -salt -pass pass:asdf > output.txt <<EOF
U2FsdGVkX1/zN55FdyL5j1nbDVt5vK4V3WLQrnHPoycCJPwWO0ei3PCrrMqPaxUH.....blablablah data
EOF
The only problem with this, that would otherwise work, is that I have to hit enter when the script reaches this position. I have tried changing the way \n are placed, but no luck.
唯一的问题是，当脚本到达这个位置时，我必须按回车键，否则会起作用。我试过改变 \n 的放置方式，但没有运气。
I can't afford to press manually enter for all the files that are going to be embedded like this one!!
对于将要嵌入的所有文件，我无法手动按 Enter 键！！
Thanks for your help!
谢谢你的帮助！

A couple of things wrong here:
这里有一些错误：
You shouldn't use both
cat | ...and also a here document (<<EOF). Use one or the other.Your example isn't testable because the example text is not the DES3 encryption of any input.
您不应该同时使用两者
cat | ...和 here 文档 (<<EOF)。使用其中之一。您的示例不可测试，因为示例文本不是任何输入的 DES3 加密。
This example works as expected:
此示例按预期工作：
cat ~/.profile | openssl des3 -e -a -salt -pass pass:asdf -out /tmp/output.txt
That is, it writes an encrypted version of ~/.profile, base64 encoded, to file /tmp/output.txt.
也就是说，它将~/.profilebase64 编码的加密版本写入文件 /tmp/output.txt。
Here's a working decryption example with a here document:
这是一个带有 here 文档的有效解密示例：
openssl des3 -d -a -salt -pass pass:asdf <<EOF
U2FsdGVkX1/03DBd+MpEKId2hUY82cLWpYltYy2zSsg=
EOF
Try this in the safety and comfort of your own home...
在您自己的家中安全舒适地尝试这个......
