KB Sriram c10c31b5e9 x/crypto/openpgp: cross-signature validation for signing subkeys.
Section 11.1 of RFC4880 requires that binding signatures on
signing subkeys contain a valid embedded signature that cross-certifies
the primary key. This is to avoid the weakness described at
https://www.gnupg.org/faq/subkey-cross-certify.html

Fixes #10740

Adam Langley 84ca184138 go.crypto/openpgp: fix user id signing.
Entity.SignIdentity used the wrong signature function and produced invalid
certification signatures. Fixed.

VerifyUserIdSignature was used for checking the self-signature on an identity,
but didn't support anything but a self-signature. This change alters the
low-level API so that checking cross-signatures is possible.

Fixes golang/go#7371.

Adam Langley eb19e229bd go.crypto/openpgp: don't select expired keys.
When selecting keys for encryption, don't select keys that have
expired.
