Always use a password manager like KeePassXC to store these passphrases. If you lose the password for an encrypted archive, there is no way to recover the data .
It is a beautiful demonstration of the Unix philosophy: small tools that do one thing well, working together to solve a complex problem. The output is a file that is useless gibberish to anyone lacking the key. It looks like a tar.gz file, but trying to open it yields only errors and noise. Only the inverse command—decrypting with openssl and then piping to tar —can reassemble the original data.
Simple encrypted Linux folders with TAR and GPG — Butlablog
PeaZip is a powerful, free, and open-source file archiver available for Windows, Linux, and macOS. It's an outstanding alternative to paid tools like WinRAR.
This command does the following:
gpgtar -c -z --symmetric --cipher-algo AES256 --gpg-args " -o my_secured_backup " /path/to/directory
This guide covers the most secure and reliable methods to encrypt your compressed archives using native command-line utilities and popular third-party tools. Method 1: Encrypting with GnuPG (GPG)
for a specific operating system, or should we look at how to this encryption in a script?
GNU Privacy Guard (GPG) is a complete and free implementation of the OpenPGP standard, making it the go-to encryption tool in the Linux world for signing and encrypting files and emails. It is exceptionally user-friendly and powerful. password protect tar.gz file

Use the following command pipeline to compress and encrypt your directory using the AES-256 encryption algorithm:
is a utility designed specifically for simple, password-based file encryption. Super User To Encrypt: tar -cvzf - /path/to/files | ccrypt > my_archive.tar.gz.cpt Use code with caution. Copied to clipboard To Decrypt: ccrypt -d my_archive.tar.gz.cpt tar -xvzf my_archive.tar.gz Use code with caution. Copied to clipboard 3. Using OpenSSL - Built-in on many systems OpenSSL can be used for AES-256 encryption. Ask Ubuntu To Encrypt: tar -czvf - directory/ | openssl enc -aes- -cbc -e > my_archive.tar.gz.enc Use code with caution.
