ParaCrypt is software for encrypting and decrypting data with one-time-pads. For convenience the one-time-encryption-pads are created using pre-shared unencrypted files as sources of entropy.
Encryption with symmetric-key algorithm Kirmah
- generate keys with exotic chars
- redefine key length
- key mark to ensure decryption capabilities
- mix data
- fast with multiprocessing
- possible compression
- gui on gtk3
- cli tool
- python3
DEPENDENCIES :
========
python3, python-gobject, gobject-introspection, pygtk
3 modes are available to encrypt :
========
- compression (full / disabled or only final step)
- random (simulate a random order - based on crypted key - to randomize data)
- mix (mix data according to a generated map - based on crypted key - with addition of noise)
Process is as follow :
========
encrypt :
file > [ compress > ] encrypt > [randomiz data > mix data > compress > ] file.kmh
decrypt:
file.kmh > [ uncompress > unmix data > unrandomiz data] > decrypt > [uncompress > ] file
========
for encrypt/decrypt large binary files, use the fastest alternative : split/merge
ImpraStorage provided a private imap access to store large files
ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key.
An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part.
transfert process is...

My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself.
I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's...
