Library Read Me

This content is provided by the library maintainer and has not been validated or approved. This fork is a valid Photon library, only SHA256 is supported at the moment.


This branch is an experiment to see how hard it is to adapt to Particle.io's Photon Device.

The Plan:

  • Copy the files into the Particle Build IDE.
  • Find where it breaks.
  • Fix dependencies - substitute and modify includes.
  • Change functions or Structures where required.

Please forgive me if I fail to use best practices in the fork, I'm new to this. Suggestions are appreciated.

Current Status:

  • SHA256 portion works on Photon.
  • To use - copy sha256.h, sha256.cpp, sha256_config.h, and Arduino.h into the Particle IDE.
  • include sha256.h in your project. For examples see: sha/examples/photon

Results of Photon Test:

  • Test: RFC4231 4.2 Hash took : 8265 micros
  • Test: RFC4231 4.3 Hash took : 8276 micros
  • Test: RFC4231 4.4 Hash took : 8273 micros
  • Test: RFC4231 4.5 Hash took : 8273 micros
  • Test: RFC4231 4.6 Hash took : 8284 micros But the result looks like Test: RFC4868 AUTH256-2 (not truncated)
  • Test: RFC4231 4.7 Hash took : 8475 micros
  • Test: RFC4231 4.8 Hash took : 8609 micros

Below this point is unaltered ReadMe from the master.

Cryptosuite is a cryptographic library for Arduino (including SHA and HMAC-SHA)

It currently supports secure hashing and hashed message authentication using SHA-1, SHA-256, HMAC-SHA-1 and HMAC-SHA-256.

Installation: Make a 'libraries' directory with your Arduino sketches folder if you do not already have one. Copy the 'Sha' directory into that directory. Restart Arduino to rescan for new libraries.

Using SHA-1:

#include "sha1.h" ... uint8_t *hash; Sha1.init(); Sha1.print("This is a message to hash"); hash = Sha1.result();

The hash result is then stored in hash[0], hash[1] .. hash[19].

Using HMAC-SHA-1:

#include "sha1.h" ... uint8_t *hash; Sha1.initHmac("hash key",8); // key, and length of key in bytes Sha1.print("This is a message to hash"); hash = Sha1.resultHmac();

The hash result is then stored in hash[0], hash[1] .. hash[19].

Using SHA-256:

#include "sha256.h" ... uint8_t *hash; Sha256.init(); Sha256.print("This is a message to hash"); hash = Sha256.result();

The hash result is then stored in hash[0], hash[1] .. hash[31].

Using HMAC-SHA-256:

#include "sha256.h" ... uint8_t *hash; Sha256.initHmac("hash key",8); // key, and length of key in bytes Sha256.print("This is a message to hash"); hash = Sha256.resultHmac();

The hash result is then stored in hash[0], hash[1] .. hash[31].

Verification: The provided example code tests against published test vectors. SHA-1: FIPS 180-2, RFC3174 compliant HMAC-SHA-1: FIPS 198a compliant SHA-256: FIPS 180-2, RFC4231 compliant HMAC-SHA-256: RFC4231 compliant

*UPDATE** Added Intel Galileo Support Added printf.h so galileo can redirect to serial all the printf requests.

*UPDATE** Raspberry pi support added
