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.
