gnupg-curl 1.4.10-4ubuntu2 (amd64 binary) in ubuntu natty

 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.
 .
 This package contains the keyserver helper tools built with libcurl,
 which replace the ones in the gnupg package built with the "curl shim"
 variant of gnupg. This package provides support for HKPS keyservers.
 .
 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).
