Files now support integrity hashes. This defuses some obscure attacks which could allow adversaries with a substantial level of access to replace safe file data on disk (trustworthy.exe) with unsafe data (evil.exe).

Additionally, we have removed internal use of SHA1 and started moving away from HMAC+SHA1. See T12515 for detailed discussion of these issues.

After upgrading, installs are encouraged to run this command to backfill integrity hashes for existing file data:

phabricator/ $ ./bin/files integrity --compute --all

This command can be run while Phabricator is online and serving requests.


  • See note about Files integrity hashes above.
