I need to implement the HASH algorithm (MD5 & SHA-1) on an 8 bit MCU. I hear it can only be implemented on 32bit and sometimes 16bits MCU. Is that possible? I will appreciate link where possible. A program in C language most preferred.
Someone answered it in another "exchange" site: http://electronics.stackexchange.com/questions/1830/md5-implementation-for-microcontroller
There you have links to C implementations, etc.
And yes, it's possible to implement MD5 and SHA1 in 8bits, you'll just have to worki with 16 (or 32) bits operations, not that hard...
