Subject [jira] Commented: (COUCHDB-558) Validate Content-MD5 request headers on uploads
Date Mon, 02 Nov 2009 22:30:59 GMT


Robert Newson commented on COUCHDB-558:

MD5 is fine for guarding against transmission errors and checking against corruption. That
is, the current uses are just fine, imo. I do expect to have to convince my PHB that using
MD5 is fine (we currently use SHA256 for essentially the same thing), but that's my sorrow,
not yours. :)

IIRC, I believe S3 uses this header (and therefore MD5) for the same purpose.

with the data and Couch validates the MD5 on arrival.
