crype – diffable/syncable encryption for files or shell pipes

What it does

Deterministic syncable/diffable encryption, for files or pipes. crype is a tool providing rsyncable deterministic-encryption (like rsyncrypto for pipes). It encrypts data using a common decision function over plaintext, allowing rsync-like tools to still work efficiently over the encrypted data. It uses HMAC-SHA1-PBKDF2 and the ChaCha stream cipher. Compression is also implemented, as this improves both portabiity and rsyncability compared to a separate gzip --rsyncable pass. See crype --help for usage instructions. Binaries are provided for 32-bit Windows, 32-bit Cygwin, and 64-bit Debian 7. Source code is made available freely under the terms of the ISC license. The source code…from code.ivysaur.me
