SAE: Add support for ECC group 21 (521-bit random ECP group) In addition to the trivial change in adding the new group ientifier, this required changes to KDF and random number generation to support cases where the length of the prime in bits is not a multiple of eight. The binary presentation of the value needs to be shifted so that the unused most significant bits are the zero padding rather than the extra bits in the end of the array.
