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
