I have updated my Java P.o.C. at 

However, there's some weirdness in 
- the record size now used appears to be 41626 (it doesn't matter a lot 
because it's a single truncated record, but still).

I assume that wasn't intentional, as the version in git has an updated 
example, but that gives me even a weirder rs.

In general I'd like the examples to be a bit more verbose - spell out 
the record size and salt (previously the salt was in a header field), 
and maybe mention what padding was used (the second example uses two 
records, where one has 0 padding bytes, and the other has 1 -- you 
really have to implement...).

Which leads me to another thought: it would be good to explain somewhat 
more when padding would be useful. In particular, if you write a library 
that implements an encoder, what would be a good way to specify padding? 
Having the same padding in every record probably wouldn't be good, right?

Best regards, Julian
