Differential D576
Cashaddr decoding the raw data and checksum Authored by deadalnix on Sep 30 2017, 10:56.
Details
This is split from D544 plus implement a candidate BCH code of degree 8 for it. The BCH code can detect up to 6 errors over the typical length of an address and up to 8 errors in a row. This is intended to serve as a base to get the new address format started. Added unittests.
