Hi, so I installed suite on my Macos ventura, I'm interested in using the package for file encryption with password.

I right click file, go to context meny click encrypt put my password in - works perfectly.

But I would like to know more about encryption algorithm, there is no information about encyrption algorithm and its not possible to tweak any parametrs. Where can I find information about encryption algorithm? Can I change default settings somehow?

Please elaborate!

    Mac GPG uses hybrid encryption. The suite generates a password at random called a session key and uses that to encrypt the file with AES, the session key is then encrypted with your RSA key and appended to the end of the file as per the common standards set by OpenPGP. The common standards are how GPG softwares are interoperable across operating systems.

    More information may be found here, https://gpgtools.tenderapp.com/kb/how-to/introduction-to-cryptography. You may change the default settings by editing your gpg.conf file which may be found at /Users/USERNAME/.gnupg using your terminal. Typing "Man GPG" in your terminal opens the user manual.

    For help editing your gpg.conf file, I recommend that you read the following,

    awesome, thank you for your reply!

    I had a look at everything, and I'm just going to stay on default settings!
