-----BEGIN PGP SIGNED MESSAGE----- The Ruby Block Cipher has just been published. It is not a general block cipher in that it cannot be used in Electronic Codebook (ECB) mode. It is more like a cryptographic hash function with a block size of only 64 bits. Of course, 64 bits is too short for a cryptographic hash function intended for digital signature use, but it is just fine for a quick block cipher. This may be a good reference for those folks who want a quick & easy encryption algorithm that need not withstand nuclear attack but can provide something better than common weak encryption methods in use in the software industry. Your comments and suggestions on this rather strange little cipher are welcome. Information on the Ruby Block Cipher is available as ftp://ftp.csn.net/mpj/public/ruby_m4.ps and, if you are in the USA or Canada, a reference implementation is in ftp://ftp.csn.net/mpj/I_will_not_export/crypto_???????/mpj/rubycode.zip where the ??????? is revealed in ftp://ftp.csn.net/mpj/README rubycode.zip is also available on the Colorado Catacombs BBS at 303-772-1062. Note: this is not a product for sale (it is free and probably worth at least as much as you pay for it). It is also not a prepublication (it is THE publication in electronic form with no paper publication anticpated in the near future). ___________________________________________________________ | | |\ /| | | Michael Paul Johnson Colorado Catacombs BBS 303-772-1062 | | \/ |o| | PO Box 1151, Longmont CO 80502-1151 USA Jesus is alive! | | | | / _ | mpj@csn.net aka mpj@netcom.com m.p.johnson@ieee.org | | |||/ /_\ | ftp://ftp.csn.net/mpj/README.MPJ CIS: 71331,2332 | | |||\ ( | http://www.csn.net/~mpj -. --- ----- .... | | ||| \ \_/ | PGPprint=F2 5E A1 C1 A6 CF EF 71 12 1F 91 92 6A ED AE A9 | |___________________________________________________________| -----BEGIN PGP SIGNATURE----- Version: 2.7.1 iQCVAgUBMNiaP/X0zg8FAL9FAQHe0AP+N+tBxoaIdny3CEgxdA8LO9+5VyYiOety qYBc9aCrCbw4TpsFTcsg5bosPlkm3H+VwpWVGOshfl5p69J893jrma07xRamEvM0 /1Mro3X/Ga4SQ7rjHPSdPCBR3YxSA7UoIx27gldTBty2k8WAAeH0BTbn/5s1bGrf ej9ab/rd7Jc= =QRjc -----END PGP SIGNATURE----- P.
