HMAC-MD5

This is an HMAC-MD5 library implementation for ESP8266 on Arduino IDE. This library uses MD5 64-byte blocksize, and 16-byte hash result.

Usage

byte msg[] = { 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88 };
byte key[] = { 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88 };

byte result[16];

void setup() {
	Serial.begin(115200);
	Serial.println("HMAC-MD5 Test");
	hmac_md5(key, sizeof(key), msg, sizeof(msg), result);

	// -------------- DEBUGGING PURPOSE ------------------
	for(int i = 0; i < 16; i++) {
		byte b = result[i];
		if(b < 0x10) Serial.print('0');
		Serial.print(b, HEX); Serial.print(' ');
	}
	// -------------- DEBUGGING PURPOSE ------------------
}
