Encryption Chip (details)

Sorry to follow up my own post, but it was brought to my attention that there are a number of encryption chips available and I would need to be more specific to get any specific information. I am looking for a chip that can do DES, Triple DES and/or Blowfish for the purpose of secure communications. We want an IC instead of software because of the volume of information that will have to be processed in this project. If anyone has any information please drop me an email Thanks Andrew Alston
