[Message part 1 (text/plain, inline)]

ALCON

Please accept attached 'SHASUB' proposal for incorporation consideration in
'coreutils'.

I recognize it has limited usage; however, there is an applicable niche for
this utility.

I have developed attached interim script-based functional prototype.

Thank you

Attila Horvath

Thanks for the proposal. You've obviously spent some time writing it up. 
However, I'm not entirely sold on the idea being worth the effort. The 
point of the currently-supported approach is that one can and should 
communicate checksums by a different (and hopefully more reliable) means 
than what's used for the checksummed data. That advantage is lost if 
checksums are communicated as part of the data. The proposed passphrases 
attempt to work around this, but if they're evanescent (as in the 
proposal) then they're unsuitable for archival data, and if they're 
permanent they take on the role of the checksums so we're no better off 
than before.
