    Kypeless

    Kypeless

    Fully decentralised secure p2p communication program

    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.

    lecithine

    FUSE File system powered by secret sharing scheme

    Lecithine is a FUSE (file system in user space) using a secret sharing scheme. You can use Lecithine as regular file system. When writing to disk, data will be devided into randomly chosen pieces (secret shares) and stored into different places. Upon reading, the shares are merged together such that in turn the plaintext results. From a cryptographers point of view, there is no symmetric or private key ever needed to produce a ciphertext. This is how secret sharing schemes are designed.

    BEDBUG CSPRNG & Stream Cipher

    BEDBUG CSPRNG & Stream Cipher

    A family of FLEA-inspired CSPRNGs and Stream Ciphers

    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...

    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...

    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.

    MLCrypt

    Simple, lightweight, standalone command-line single file encryption.

    Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit...

    chaOS41

    A cryptocurrency like Bitcoin improved upon with reality binding.

    There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted.
