Apple has posted a new support document, which includes the company’s own public PGP key for encrypted security emails originating from Cupertino.
Apple noted that its current PGP key will be valid until May of 2018. PGP, or “pretty good privacy” is one of the most popular encryption schemes in general use today, through both the PGP Corporation and the open source GnuPGP. Apple posted links to both. You can subscribe to Apple’s Security-announce emails at Apple’s website.
More from Apple:
Documents developed by the Apple Product Security team are signed with the Apple PGP key. We encourage you to check the signature to ensure that the document was indeed written by our staff and has not been changed.
Note for users of the security-announce mailing list:
Some mail programs cause changes to messages, resulting in an indication that the PGP signature is not good. Critical information will also be posted to our web site along with a PGP signature, providing you with a confirmation of authenticity.
