Password encrypted files in Linux

No Comments »


I am found of keeping password protected backups and most of the time I lost my super secret password thus unable to open my super important backups 🙂 just kidding.

Like in windows we can simple right click and zip folders/files with passwords in text based terminals of linux I always want the same.

So here is the trick I normally use.

For encrypting a file:

openssl enc -aes-256-cbc -e > out.file

It will ask for password like:

enter aes-256-cbc encryption password:
Verifying - enter aes-256-cbc encryption password:

If you want to encrypt a folder with compression (tar.gz)

tar -cz foldername | openssl enc -aes-256-cbc -e > out.tar.gz

Now the important part, decrypting your encrypted files….

openssl enc -aes-256-cbc -d -in out.file > new.file
