GnuPG (GNU Privacy Guard) is a widely used free software encryption system that implements the OpenPGP standard to provide secure communication and data protection across multiple platforms. It uses a hybrid cryptographic approach combining symmetric encryption for performance with public-key cryptography for secure key exchange and identity verification. The software allows users to encrypt files and messages, create digital signatures, and manage cryptographic keys, making it a foundational tool for privacy-focused workflows. Because it is open source and licensed under the GNU GPL, GnuPG can be freely audited, modified, and redistributed, which has contributed to its adoption in security-sensitive environments. ...

...Themis hides cryptographic details and eliminates popular mistakes. Themis provides ready-made building blocks (“cryptosystems”) for secure data storage, message exchange, socket connections, and authentication. Secure Cell is a multi-mode cryptographic container suitable for storing anything from encrypted files to database records. Use Secure Cell to encrypt data at rest. Secure Cell is built around AES-256-GCM, and AES-256-CTR. Secure Message is a simple encrypted messaging solution for the widest scope of applications. ...

...It includes a complete GNU/Linux OS and a graphical web interface for user and administrative access. It comes in the form of virtual machine templates.. - fully compatible with any SMTP mail server (Exchange, Zimbra, O365,...)

...It integrates these components in an innovative way that makes secure protocol design relatively simple. With the included elliptic curve code, STROBE additionally supports asymmetric key exchange and digital signature creation and verification.

This is a source repository for the ThreeBears family of post-quantum key exchange and encryption algorithms.

MikroLock is a fast native implementation of the open minilock file format (https://minilock.io). Despite its name (and in contrast to the original implementation), it can also handle BIG files.

Kypeless encapsulates strong symmetric and asymmetric cryptography so you can get the benefits of secure communication following some simple steps. Right now, Kypeless is unstable pre-alpha software, published only for testing purposes. Kypeless allows you to exchange instant messages, long not-so-instant messages and files, but a lot more features are planned to be implemented later.

See http://silcnet.org/ for detailed information. SILC provides common chat and conferencing services like private messages, instant messages, channels and groups, and video and audio conferencing. The main difference to other protocols is that SILC has been designed with security as its main feature. All packets and messages sent in SILC network are always encrypted. Private messages are encrypted end-to-end, channel message are encrypted with channel-wide secret key and secure...

One of the first secure telephony programs. Not limited to VOIP but can also directly encrypt a telephone line by using modems. Calls are encrypted using Diffie-Hellmann key exchange and several symmetric ciphers. Download is possible from Germany only, see homepage

Tool used for analyse DHCP packets exchange, detecting rogue servers and server attack.

LibIDMEF is an implementation of the Internet Engineering Task Force (IETF), Intrusion Detection Exchange Format Charter Working Group (IDWG), draft standard Intrusion Detection Message Exchange Format (IDMEF) protocol.

SIPES (Security Incident Pollicy Enforcement System) aims to provide an automated e-mail,XML and PKI based system for automated security policy enforcement based on statefull risk assesment and open exchange formats.

The NEO Project uses the NEO-c (Network Exchange Operation for Charity) platform to participate in various computing challenges and projects, and donates any winnings to the charities specified by its users.

CryptKit is a small, fast cryptographic toolkit for python. It implements Rijndael(AES), SHA 256, Elliptic Curve PKI, Diffie-Hellman key exchange and Nyberg-Ruppel signature/verification. Comprehensive enough to provide a secure socket alternative to SSL

iSSL is a minimalistic cryptographical API that uses the ciphers RSA and AES to establish SSL-alike, secure encrypted communications between two peers communicating through a network socket, including session key generation and public key exchange.

Huskarl is an alternative authentication and key exchange schema for Bluetooth devices.Huskarl produces secure shared link keys between two devices using public key cryptography.
