gnupg 1.4.10-2ubuntu2 (amd64 binary) in ubuntu maverick

 GnuPG is GNU's tool for secure communication and data storage.
 It can be used to encrypt data and to create digital signatures.
 It includes an advanced key management facility and is compliant
 with the proposed OpenPGP Internet standard as described in RFC2440.
 .
 The gnupg package is built without libcurl. So it does not support
 HKPS keyservers. Install the gnupg-curl package if you want to use
 the keyserver helper tools built with libcurl and supporting HKPS.
 .
 GnuPG does not use any patented algorithms. This means it cannot be
 compatible with PGP2, because that uses IDEA (which is patented in
 a number of countries).
