Regarding the existance of brute force machines. The other player, AFAIK, is jumping straight to ASIC. Adam ----- Forwarded message from staym () accessdata com -----

AccessData is building a massively parallel computer to break Word & Excel documents (and DES for kicks) out of FPGA's and DSP's; the estimates on the 40-bit RC4/MD5 authentication MS uses are ~20,000 keys/sec/chip, with 64 chips per box, or ~1.3 million keys/box/sec. The boxes will cost $6-8K, depending on the chip and quantities. For DES, we'll only be at ~1.2 billion keys/box/sec; we're hoping that once we have this proof-of-concept (i.e. the parallel processing boxes) and all that overhead taken care of, someone will foot the bill for developing the ASIC chip (1000% faster, at least) and we can plug-'n-play:-) -- Mike Stay Cryptographer / Programmer AccessData Corp. mailto:staym () accessdata com ----- End of forwarded message from staym () accessdata com ----- -- "It is seldom that liberty of any kind is lost all at once." -Hume
