How do I password protect / encrypt a file within Linux using OpenSSL ?
The file we will encrypt will be the file secretfile.txt.As you can see it is just a plain text file.
Use the openssl comand to encrypt your file and then test the new file is fully encrypted.
$ openssl aes-256-cbc -salt -in secretfile.txt -out secretfile.txt.aes
enter aes-256-cbc encryption password:
Verifying – enter aes-256-cbc encryption password:
$ cat secretfile.txt.aes
Decrypt the file and then confirm the decypted file is readable.
$ openssl aes-256-cbc -d -salt -in secretfile.txt.aes -out secretfile.txt
enter aes-256-cbc decryption password:
$ cat secretfile.txt
This is a secret file that we do not want anyone to read.

sl is also aesthetically pleasing due to attention to layout and filtering as well as limiting color and text annotations to salient information.
