Where can I find it?

SVN: [1]

via Track (also svn, but suitable for direct browsing):[2]

Short Facts

  • small implementation of cryptographic algorithms in C (quite protable)
  • even smaller implementations in assembly language (ATmega, gnu-avr-as)
  • allfunctions are reentrant (except functions of the PRNG "Entopium")
  • license: GPLv3 (nearly everything) (for different licensing contact author)

About

Crypto-avr-lib is a set of implementations of different cryptographic primitives. Due to the special limitations of microcontrollers (very raw space, RAM and flash are ranging from a few bytes to a few KiB) reference or "normal" optimised implementations are not useable. Therefor we try to provide special implementations which respect the extrem limited resources of microcontroller applications.
