Class loading of PGP functionality has never worked out of the box,
from which we can conclude that this feature is unused in the wild.
PGP functionality has never been located in bcprov-*.jar, at least as
long as the original library download configuration has existed.
3bccd773 points to bcprov-jdk16-144.jar, which does not contain PGP
classes:
$ curl -sOL http://www.bouncycastle.org/download/bcprov-jdk16-144.jar && jar tf bcprov-jdk16-144.jar | grep -i pgp
org/bouncycastle/crypto/modes/OpenPGPCFBBlockCipher.class
org/bouncycastle/crypto/modes/PGPCFBBlockCipher.class
Even before that commit, in 44671f5c, we were checking for the
presence of PGPPublicKey.class in the havePGP() helper method.
This functionality at one point was used by Google to implement CLA
checking, but that used a different build system and so did not see
the breakage caused by incorrect library download configuration. These
days, Google does not even use the same contact store mechanism for
googlesource.com; CLAs are managed using a different system.
Also delete UI associated with storing contact information. Although
it was possible to configure a CLA to prompt the user for contact
information, looking at the logic in AccountSecurityImpl, this info
was dropped on the floor unless a ContactStore was configured. As we
know, this was never the case, so claiming to store encrypted contact
information in the UI was basically a lie.
Similarly, the contactFiledOn field in Account was only set in the
same ContactStore-enabled codepath, so we can kill that as well.
