7-Zip uses strong AES-256 encryption to protect files inside compressed archives. Here’s how it works:

Key Features of 7-Zip Encryption:

1.AES-256 Encryption:

7-Zip uses the Advanced Encryption Standard (AES) with a 256-bit key length, making it very secure against brute-force attacks.

2.Password Protection:

When you create an archive with 7-Zip, you can set a password. This password is required to access the contents of the archive and is not stored in the file, enhancing security.

3.File Header Encryption:

7-Zip can encrypt not just the contents of the files but also the file names and directory structure (if you choose to do so), which adds an extra layer of privacy.

4.Encryption Options:

 Users can choose to create either encrypted archives (which will keep contents secure) or regular archives (no encryption).

Advantages of 7-Zip Encryption:

•It has very good security as AES-256 is considered one of the safest encryption methods available.

•Users can apply or remove encryption easily while creating or modifying archives.

•It is free and open-source, meaning it’s free from the restrictions of any single company, hence its security practice is more transparent.

•Password Recovery: If the password is forgotten, recovering the files can be challenging, as AES-256 is designed to withstand unauthorized access.

•Compatibility: While 7-Zip is widely compatible, other software may have trouble opening AES-encrypted 7z files, so ensure your recipients can use compatible tools.
