Z1 SecureMail Messenger is a server-based software solution for confidential email exchange. It enables secure communication to everyone at every place. It acts as an SMTP proxy and is completely transparent for the sender. It either delivers the message as an encrypted PDF document or stores the message on the server and provides comfortable access via Web frontend. The recpient can read the secured message with familiar software (Web browser, PDF reader). No PKI technology or certificates are required. Evaluation packages for Debian and Solaris are available for download.
StoneVPN is a system that makes it easy to create certificates and configuration files for use with an OpenVPN server for both Windows and Linux users. It has the ability to create a zip file and e-mail the entire package to a user. It uses pyOpenSSL and custom patches that allow it to manage a CRL file.
MEO is a powerful data encryption application to encrypt or decrypt files of any type, including Microsoft Word, email, and PDF documents. It can also create self-extracting encrypted files. This is handy for those who like to view their encrypted files without installing any other encryption software. Also, many downloads supply a checksum or hash value for you to verify the integrity of your download. Meo allows you to create and verify MD5 checksums, SHA-1 hashes, and Tiger Tree hashes.
sha_digest is an implementation of the secure hash algorithms SHA-1, SHA-224, SHA-256, SHA 384, and SHA-512 as described in the FIPS 180-3 standard. It is written in standard compliant C (ANSI C89) and system- and architecture-agnostic. Byte- as well as bit-oriented hashing is supported. The package can be used as a shared library or its modular components can be integrated directly into other projects.
Perl Math::FastGF2 is a Perl math module for performing arithmetic on Galois Fields. Galois Fields have applications in Cryptography (such as the AES encryption system or various threshold systems for sharing secrets) and Error-correcting Codes (eg, Rabin's Information Dispersal Algorithm or Reed-Solomon Codes). It currently implements all the primitive maths operations needed to work with Galois Field polynomials. A set of demo scripts is included that implements Shamir's Secret Sharing algorithm using the module.
CryptoTE is a text editor with integrated strong cryptography. It is based on the popular Scintilla widget and automatically stores text data in secure encrypted container files. Compared to other "password keeper" programs, CryptoTE does not force any structure upon your data: it works with plain ASCII text and does not require you to fill in grids, key-value attributes, or descriptions. Encryption is transparently performed using the highly-secure Serpent cipher. The editing interface is thoroughly optimized for speed and ease of use. Multiple subfiles, Quick-Find, and a two-click random password generator make daily use very convenient.
rfc3394 is a C# implementation of the RFC 3394 key-wrapping algorithm. The associated assembly provides two simple operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which, among other things, ensures that the implementation is verified against the test vectors provided in RFC 3394.
