Dear NEM Mates,
Developers should pay attention to an important point regarding SHA-3,
SHA-3 standard has been updated by NIST, so NEM now use the old implementation, called SHA-Keccak.
Using the new implementation will lead to lot of confusions and coins lost and each version will generate a different address for the same public key.
Spongy Castle updated their SHA-3 implementation since the 53 version.
We faced this issue when we were about to update the android wallet, so i wanted to rise a flag about this ambiguous point.
A possible related issue has been reported in the following issue in the android wallet repo:
More tech details are available in my last comment in the Spongy Castle issue:
