    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...

    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...
