This will prompt you to enter a password to encrypt the file.
openssl enc -aes-256-cbc -d -salt -pbkdf2 -in secure_archive.tar.gz.enc | tar -xzf - Use code with caution. : Tells OpenSSL to decrypt the incoming file. 3. Alternative: Use Native Encrypted Formats (Zip / 7z) password protect tar.gz file
I have to be honest in this review: the native tar command itself (without piping to external tools like OpenSSL or GPG) has a checkered history with passwords.

If you use Windows' built-in "Send to > Compressed folder" and add a password, it still uses the broken ZipCrypto (not AES). Always use 7-Zip, WinRAR, or the command line for real AES-256 on Windows.
GPG will prompt you for the password and extract the files directly into your current directory. Method 2: Encrypt with OpenSSL Copied to clipboard If you use Windows' built-in
How to password protect a tar.gz file depends on whether you want a built-in solution or a more secure, modern approach. Since the standard tar utility does not have a built-in password feature, you typically have to pipe it into an encryption tool like or OpenSSL . 1. The Standard Method: Using GPG (Recommended)
gpg -d encrypted.tar.gz | tar -xzf -
Not a .tar.gz ; standard Zip encryption is weaker than GPG (use -e for basic or specialized flags for AES). Verdict: Which should you use? GPG (GnuPG) Security ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐ Ease of Use Portability
