%description
    PGP (Pretty Good Privacy) is a public key encryption program originally
    written by Phil Zimmermann in 1991. This is version %{V_long}, considered
    a classic PGP by some and outdated by others. However, this version of PGP
    is absent of questionable security features implemented in more current
    releases. Because of this, some paranoid PGP users prefer this classic
    version. An article http://senderek.de/security/key-experiments.html
    explains the questionable security features of newer versions of PGP, and
    the reasons that PGP %{V_long} might be the most secure version to date.

    This version includes '4k' patch code from Rich WALES. It will not display
    warnings regarding RSA patent rights, and allows key generation and
    processing of up to 4096 bits in length. For more information, please see
    http://www.richw.org/pgp/263i-4k-patch.
