Hi Paul,

thank you for your review comments. Here I am addressing one that can be 
easily answered.

Byte order doesn't come into play in the encoding of the string. 
"OpenPGPCompositeKDFv1" is a string of characters, when encoded into 
ASCII that happens byte by byte so naturally in the same order. The 
command output you posted is itself an artifact, as hexdump by default 
groups the bytes into sets of two and then inverts the order.

Use

echo -n OpenPGPCompositeKDFv1| hexdump -C

to get byte wise output and you will see that it matches the byte string 
in the draft.

Best regards,
Falko
