Parameters
+ + + +
keyPoints to the HMAC key for the hashing process.
keyLenSize of the HMAC key in bytes.
+
+
+

The following example computes a HMAC over a series of data blocks with a specific key:

+
hash.resetHMAC(key, sizeof(key));
+
hash.update(data1, sizeof(data1));
+
hash.update(data2, sizeof(data2));
+
...
+
hash.update(dataN, sizeof(dataN));
+
hash.finalizeHMAC(key, sizeof(key), hmac, sizeof(hmac));
+

The same key must be passed to both resetHMAC() and finalizeHMAC().

void BLAKE2s::resetHMAC (const void * key,

Resets the hash ready for a new HMAC hashing process.

+
Parameters
+ + + +
keyPoints to the HMAC key for the hashing process.
keyLenSize of the HMAC key in bytes.
+
+
+

The following example computes a HMAC over a series of data blocks with a specific key:

+
hash.resetHMAC(key, sizeof(key));
+
hash.update(data1, sizeof(data1));
+
hash.update(data2, sizeof(data2));
+
...
+
hash.update(dataN, sizeof(dataN));
+
hash.finalizeHMAC(key, sizeof(key), hmac, sizeof(hmac));
+

The same key must be passed to both resetHMAC() and finalizeHMAC().

Parameters
+ + + +
keyPoints to the HMAC key for the hashing process.
keyLenSize of the HMAC key in bytes.

The following example computes a HMAC over a series of data blocks with a specific key:

hash.resetHMAC(key, sizeof(key));
+
hash.update(data1, sizeof(data1));
+
hash.update(data2, sizeof(data2));

...
+
hash.update(dataN, sizeof(dataN));

hash.finalizeHMAC(key, sizeof(key), hmac, sizeof(hmac));
+

The same key must be passed to both resetHMAC() and finalizeHMAC().

    Then in the setup() function we call RNG.begin() to start the random number generator running and call RNG.addNoiseSource() to register all of the application's noise sources:

    The begin() function is passed two arguments: a tag string that should be different for every application and an EEPROM address to use to load and save the random number seed. The tag string ensures that different applications and versions will generate different random numbers upon first boot before the noise source has collected any entropy. If the device also has a unique serial number or a MAC address, then those can be mixed in during the setup() function after calling begin():

    The random number generator needs 49 bytes of EEPROM space at the specified address to store the previous seed. When the system is started next time, the previous saved seed is loaded and then deliberately overwritten with a new seed. This ensures that the device will not accidentally generate the same sequence of random numbers if it is restarted before a new seed can be saved.

    By default the seed is saved once an hour, although this can be changed with RNG.setAutoSaveTime(). Because the device may be restarted before the first hour expires, there is a special case in the code: the first time that the entropy pool fills up, a save will be automatically forced.
