When I wrote such code, it seemed that the algorithms were written for a 32
bit word.

Might you have fields without explicit sizes that are bigger on a 64 bit
platform? Check the generated assembler.

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
