testssl.sh is a free command-line tool that checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. testssl.sh is free and open-source software. You can use it under the terms of GPLv2, please review the License before using it. Works for Linux, Mac OSX, FreeBSD, NetBSD and WSL/MSYS2/Cygwin out of the box, no need to install or configure something, no gems, CPAN, pip or the like.

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate...

This project now hosts the third-generation of Java SSH API, Maverick Synergy. This API builds on the Maverick Legacy commercial APIs and delivers a new API in a unified client/server framework. This API is available to the community under the LGPL open source license. This update includes ed25519 support, support for the new OpenSSH private key file format and stronger key exchange algorithms. The project continues to host both the original API and legacy applications created around...

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage.

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a...

MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

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

Alkindus is an automated solver for short monoalphabetic substitution ciphers without word divisions.

Implementation of Rijndael, RSA and El Gamal ciphers as well as SHA256, Blake and Blue midnigh wish hash functions. The program is for encrypting files but it can be rewritten for other purposes.

Utility to encrypt files and streams. Features: encryption with AES, Serpent, Twofish and many other block ciphers supported by Botan; PBKDF2 key derivation; HMAC verification; does not require files, works with pipe input and output

Vernash: Stream cipher based on the Vernam cipher and Variable-Length Hashes

SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.

SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.
