    Axcrypt vs GnuPG opinions
    This alternative is disputed. Axcrypt is still a legitimate alternative to GnuPG, but it might have issues that some users think are important.

    As far as I see, Axcrypt is a file encryptor. But GnuPG (and PGP generally) is targeted mostly for email body encryption and signing: not only files and not only encryption. Also, Axcrypt is for Windows only.
