    sha3sum and then some

    sha3sum - A demonstration of the Keccak permutation.

    Hash mode interface to the Keccak code package. This program illustrates the use of the Keccak permutation. Usage is much more than a hash function. The NIST compatible settings are subject to change when they publish FIPS PUB 180-5. I wrote this program when evaluating the permutation and developing tree hashing for the Intel(R) MIC architecture.

    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.
