Hi All,

Has anyone ever tried doing encryption on ARM?

I want to encrypt a file before sending it out. So far I have coded 
SHA-1 on ARM to give a 160-bit hash of the file but I cant find any 
code examples for DSA or RSA for digitaly signing the hash.

Have spoken to ARM and tried hacking out the routines from GNU and 
other open sources, but no success yet...

Any thoughts or links greatley appreciated.

Mark.

I did TEA on LPC900, but it's not close to SHA. My goal was smallest code.

Don't use TEA. If you need small code use XTEA
Are you sure you want to use RSA? RSA will run slow. I guess 
depending on how much data you want to encrypt!
