Re: scrypt Internet Draft

Hi team-scrypt!

I'll read  the spec more carefully once I'm back home, but quickly...

Is there a spec for the crypt function/command line format?  Oddly the
best spec I've seen is the PHP function by the same name.


FreeBSD has some details as well

and Ulrich Drepper's crypt sha-256/sha-512 impl:

Ideally I'd like a crypt-like format e.g. such as $7$... that
represents scrypt with related parameters.  Given that Ulrich Drepper
just wrote a txt file, and didn't appear to submit to an official
standards body, I suspect that there is no standard.

Any tips here, or possibility of adding an appendix to this spec
documenting a crypt-style format?  Or is this done, and I'm just not
seeing it?
