SILC Crypto Toolkit (SCT) is a high performance multipurpose cryptographic toolkit for application programmers. It provides ciphers, hash functions, public key cryptosystems, MAC algorithms, multi-precision integers, cryptographic accelerators, an ASN.1 encoder and decoder, and many other features.
jEncrypt is a commandline file encryption archiver. Files are encrypted with the AES-CTR mode, which was recommended by the National Institute of Standards and Technology in 2001 (NIST SP 800-38A). AES-CTR mode only provides confidentiality. It requires a message authentication code such as CBC-MAC to ensure an encrypted message is not accidentally modified or maliciously tampered with, which jEncrypt currently does not provide.
Lite Security Module is a daemon to handle Secure Boxes (files containing cryptographic keys, X509 certificates and data objects), accessible through a PKCS#11 shared library, and supporting the development of non-certified (i.e. lite) software security modules (SSM) or hardware security modules (HSM).
Sleutel is a multi-platform password manager that is written using the Eclipse Rich Client Platform (RCP). Its goal is to manage password/ID pairs for accessing Web sites and to provide an example RCP application. It features configurable password generation, labeling of password entries (a la GMail), an intuitive UI following the Eclipse model, merge capabilities, and the ability to track usage count and dates of password entries. Sleutel is the Dutch word for key.
HAVEGE (HArdware Volatile Entropy Gathering and Expansion) is a user-level software unpredictable random number generator for general-purpose computers that exploits modifications of the internal volatile hardware states as a source of uncertainty. It combines on-the-fly hardware volatile entropy gathering with pseudo-random number generation. The internal state includes thousands of internal volatile hardware states and is merely unmonitorable. It can support several hundreds of megabits per second on current workstations and PCs.
