FileCrypt enables strong security and authentication between servers. It allows IT Administrators to integrate automatic encryption and digital signing into almost any critical application. It fully supports the OpenPGP standard and is compatible with all PGP software. It also supports X.509 certificates and features a commandline interface, symmetric encryption, keyring management, creation of customizable key pairs, key revocation, key posting, file wiping, and many other useful features. An Additional Decryption Key is also supported to provide data recovery in the event of lost keys.
SocketW is a cross platform (Linux, FreeBSD, Unix, Win32) C++ streaming socket library that supports Unix sockets and TCP/IP sockets with optional SSL/TLS (OpenSSL) support. It makes it possible to write portable and secure network applications quickly without needing to spend time learning low-level system functions or reading OpenSSL manuals.
yesCoder is a program to hide data in ASCII text files. It can also be used to format ASCII text files. Hiding data means that the data is coded into an ASCII text file. The idea is that this ASCII text file (a poem, a story, technical documentation, etc.) looks so innocent that no one would guess that therein is some interesting data. If you have the need to hide some data like passwords, accounts, phone numbers, etc., so that no one can find it, yesCoder is the right tool for you. You even may send this coded data to other persons via email.
tarmill compresses and encrypts tar archives, and is designed for use in backup scripts. Unlike most other solutions, each archive member is handled separately, so damage in the middle of the archive does not render the rest of the archive unusable; it is possible to resume at the next readable member header. Compressed and encrypted archives remain valid tar files, so any well-behaved tar implementation will be able to list (but not extract) them.
quepasa is a program and method of generating unique passwords for Web sites automatically. The user remembers a single passphrase and it can generate the same password from a combination of the passphrase and the name of the Web site. This means that remembering a single passphrase will cover all the Web sites you visit. The passwords are generated automatically using SHA-256 to generate a cryptographically secure password.
The libsrtp library is an open-source implementation of the Secure Real-time Transport Protocol (SRTP) from Cisco Systems, Inc. SRTP is a security profile for RTP that adds confidentiality, message authentication, and replay protection to that protocol. It is specified in RFC 3711.
