How to encrypt a file on mac for password protection?

While Archive Utility offers a quick and easy way to encrypt a file on Mac, it’s not suitable for sensitive data requiring robust security. For stronger encryption, consider using dedicated tools like 7-Zip (via third-party apps), or FileVeult (for disk encryption).

Disadvantages of Using Archive Utility to encrypt a file on Mac:

• The built-in encryption provided by Archive Utility typically uses older or less secure encryption methods (like Zip 2.0 encryption), which are considered weak by modern standards. This means your data could potentially be decrypted with sufficient effort.
• It relies solely on password protection, which can be vulnerable if a weak password is used. Strong, complex passwords are essential but may not fully mitigate security concerns.
• Unlike dedicated encryption tools, Archive Utility offers no options for multi-factor authentication, key management, or detailed encryption settings.
• Encrypted ZIP files created with Archive Utility might not be compatible with all ZIP tools or may require the recipient to use macOS or compatible software to decrypt, which could cause issues in cross-platform sharing.
• The utility encrypts the entire archive, not individual files within it. If someone gains access to the archive, they need the password to extract any content.
• ZIP encryption does not verify the integrity of the data beyond basic checks, leaving room for potential tampering or corruption going unnoticed.
