Seccure

seccure is free software published under the GNU General Public License (GPL). To my best knowledge none of the implemented algorithms and cryptographical schemes (ECDH, ECIES, ECDSA, AES-CTR, SHA256, SHA512) is covered by software patents (see the Patent statement). All the named algorithms and all underlying elliptic curves (standardized by NIST and SECG) are considered cryptographically secure nowadays. seccure received two security audits [1,2] by the Debian auditing team in August 2006, none of them detecting a problem.
