Most of the texts I have read indicate that Triple-DES does overcome the weakness in DES. The weaknesses I have read about indicate that most of the problem is with the relatively small key size. These same texts indicate that the restrictions placed on the keysizes in exportable version of RC2 and RC4 make them relatively easy to break quickly and therefore useless for long term protection of sensitive information transmitted electronically. -- Stan | Academ Consulting Services |internet: sob@academ.com Olan | For more info on academ, see this |uucp: bcm!academ!sob Barber | URL- http://www.academ.com/academ |Opinions expressed are only mine.
