Do you know any public implementation of DES encryption algorithm in ANSI C or C51 assembler ? And other one efficient ? Thanks Javier
A DES example program comes with the C51 compiler. Have you checked the examples directory? Jon
The Triscend E5 comes with DES "soft modules" which can be implemented in the device's on-chip configurable logic
Yes. I have one on my web site. (http://www.phaedsys.org "ciphers" button) It is in C51 assembler. It is one I have used and to the best of my knowledge public domain. You will have to satisfy yourself that it works with your own test suite.
