asciilifeform: 'The cracker is built out of surplus Grass Valley HD video transform boards, scrapped by GV because of defects. A useful tool was developed to assist the board reverse-engineering effort.'
asciilifeform: 'NSA@home is a fast FPGA-based SHA-1 and MD5 bruteforce cracker. It is capable of searching the full 8-character keyspace (from a 64-character set) in about a day in the current configuration for 800 hashes concurrently, using about 240W of power. This performance is equivalent to over 1500 Athlon FX-60 CPUs, which would take about 250kW.'
asciilifeform: (summary: article elementarily demonstrates that a hash of the sha1 type could be designed with trapdoor. and then argues nonsensically that we 'know' there could have been none such.)
asciilifeform: Just before SHA-1, NSA designed SHA-0, for which weaknesses were quickly identified by the research community ... ... [claptrap snipped]'
asciilifeform: ... The original SHA-1 constants are “nothing-up-my-sleeve-numbers“, derived from the binary representation of the square roots of 2, 3, 5 and 10 ...
asciilifeform: 'Did NSA use this trick when creating SHA-1 in 1995? We believe this is unlikely, for
