A Hybrid-CPU-FPGA-based Solution to the Recovery of Sha256crypt-hashed Passwords

This paper presents an accelerator design for the password recovery of sha256crypt based on hybrid CPU-FPGA devices. By applying the brute-force attack computation model proposed in this paper, we decompose the sha256crypt function into two types of operations, namely the data dispatching and the b...
