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.
