Hello experts, Have you come across any source code for a "Digital Signature Algorithm" (DSA). I've coded a SHA-1 from sources found on the forum (thanks!) but need the private/public keys that DSA provides too. Found lots of open source DSA and SSH sites but it's mainly for operating systems. Have tried hacking out enough code for an embedded target but no joy so far... Links and hints very much appreciated. Best regards, Malcom.
Hi. You look at it..... http://www.efton.sk/crypt/51/tea.a51 http://www.efton.sk/crypt/51/tea_i.a51 http://www.efton.sk/crypt/51/xtea.a51 http://www.efton.sk/crypt/51/xtea_i.a51 There is more files for RSA crypts.
Hello, I had seen the TEA implementations before and whilst it is very compact the encryption is based on DES which has a 56-bit key. I need at least 128-bit which is why I am asking for DSA... Triple DES would do it.. I'll keep looking :-) Thanks, Malcom
