Perhaps the 'secret' data (easage0.0.1) is causing this but I can not think of any reason that the format would matter.

@Teteros Please verify whether or not 601686ca8aebc8f50d723064504b2c0115514c2d has fixed this issue.

Edit: That did not solve the issue.

Ok @Teteros cd55deeb4c5231f563b15725284a407479760b77 should have solved this.

Please let me know your verdict!

Teteros commented 6 years ago

It looks like md5sums of easage packed BIGs are matching now with sources for all test data I tried, well done!
