Arandomd is a network daemon that provides statistically tested output from a single ARC4 stream cipher generator to anyone able to connect to its listening TCP port. As multiple consumers cause it to reseed itself from a separate, strong random source, it is expected to produce consistently unpredictable results for cryptographic purposes. A configurable number of tests from the Statistical Test Suite for Random and Pseudorandom Number Generators must be passed before output data is sent to the client. It may be be useful in low-entropy environments, such as compute clouds, for generating high quality key material for strong cryptography.
FroZenLight interrelates line arts, mathematics, and cryptography. Circular shaped mirrors which are arranged in a grid-like manner reflect a light ray according to the reflection law of geometric optics. While random positions of the light source produce chaotic reflection patterns, it is possible to position the light source so that beautiful symmetric reflection patterns are created.
Caume Data Security Engine is a REST API platform for storing and processing files in uncontrolled environments. It provides a Free Software solution which allows the creation of reasonably secure and isolated workspaces to process and store sensitive data within uncontrolled environments. With concepts such as "the cloud" and "bring your own device", as well as an increasing demand for mobile devices, it has become clear that the way in which companies operate is changing dramatically, and, with it, the way in which we secure information and the infrastructure which supports business processes. CaumeDSE has been designed as a service platform which provides security to data by using free, well-known, and robust cryptographic software, as well as open and simple data structures and interfaces to make portability and extensibility easy.
vpnd is a daemon which connects two networks on network level either via TCP/IP or a (virtual) leased line attached to a serial interface. All data transfered between the two networks are encrypted using the unpatented free Blowfish encryption algorithm with a key length of up to 576 bits (may be downgraded to a minimum of 0 bits to suit any legal restrictions).
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.
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.
PolarSSL is a light-weight cryptographic and SSL/TLS library written in C. PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) applications with as little hassle as possible. Loose coupling of the components inside the library means that it is easy to separate the parts that are needed, without needing to include the total library. PolarSSL is written with embedded systems in mind and has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. The source is written to have very loose coupling, enabling easy integration of parts in other software projects. Very loosely coupled cryptographic algorithms for MD2, MD4, MD5, SHA1, SHA-256, SHA-512, AES, Camellia, DES, Triple DES, ARC3, and RSA are included.
