Version 1.0; 2014-03-31
Omega Crypt (ocrypt) is a novel password hashing and key derivation function designed in the general spirit of sequential memory-hard functions. Tunable memory usage and time (computation) parameters give ocrypt many of the anti-ASIC and anti-FPGA properties of scrypt. ocrypt is designed to defeat stream processing architectures like GPUs by using the output of a stream cipher to drive secure data-dependent branching while carefully avoiding the obvious side-channel issues with data-dependent execution.
