    EasySSL

    EasySSL is a library that can establish an SSL/TLS connection

    EasySSL is a C++ free open-source library that enables you to establish an encrypted SSL/TLS connection. You may use EasySSL for a client or a server. EasySSL is made to be simple to use, and always supplies default classes that provides full security. EasySSL is fully documented and won't overwhelm you with numerous functions and classes. EasySSL is a wrapper of OpenSSL or GnuTLS (two different releases), and thus relies on them to provide encryption.

    SES Super-Encypherment Scrambler

    SES Super-Encypherment Scrambler

    SES brings back the uncrackable onetime pad, with a digital twist.

    SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to...

    The MOTET Cipher & SE Scrambler

    The MOTET Cipher & SE Scrambler

    A tiny, fast encryption tool in C

    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. A unique nonce IV guarantees that...

    AUM CSPRNG & Stream Cipher

    AUM CSPRNG & Stream Cipher

    A minimal CSPRNG reflecting the Zen of cipher design

    AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

    ISC - The ISAAC Stream Cipher

    ISC - The ISAAC Stream Cipher

    ISC lets you encrypt & decrypt text and files of any type up to 4GB

    ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any...

    Bigram Table Generator

    Bigram Table Generator

    A program to generate random reciprocal bigram tables

    A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to...

    innocence-java

    Replace text with POS equivalent text, in a reversible fashion.

    Program takes (currently) english text sentences, and replaces each word in a given sentence with another word having the same Part of Speach (POS) tag. This creates a new sentence containing none of the original words. This new sentence can then be transmitted to a remote user, and using the same software, "de-crypted" into yielding the original sentence. The software relies on having a known "seed" value for the random number generator, which is known only by the sender and...
