Initial import of seccure-0.4 into the Packages Collection.

	The seccure toolset implements a selection of asymmetric
	algorithms based on elliptic curve cryptography (ECC).  In
	particular it offers public key encryption / decryption,
	signature generation / verification and key establishment.

	ECC schemes offer a much better key size to security ratio
	than classical systems (RSA, DSA).  Keys are short enough to
	make direct specification of keys on the command line possible
	(sometimes this is more convenient than the management of
	PGP-like key rings).  seccure builds on this feature and
	therefore is the tool of choice whenever lightweight
	asymmetric cryptography -- independent of key servers,
	revocation certificates, the Web of Trust or even
	configuration files -- is required.
