Hash: SHA512
For trac.torproject.org, 2019-11-07, afternoon:
Please add ahf to the LDAP groups: gitweb and gitolite.
Please also give ahf access to the external-services-git passwords in
tor-passwords.git by re-encrypting that file.
I would believe that the fingerprint for ahf's GPG key is:
1C2A7A3D5A8548B4ADEFD52AF9BC2FE22B08CE8F
though I have not verified this myself, enough people I trust to verify it that
I have verified myself have.
