How are primary key binding signatures (0x19) handled by gpg?

According to RFC 4880 "For subkeys that can issue signatures, the subkey binding signature MUST contain an Embedded Signature subpacket with a primary key binding signature (0x19) issued by the subkey on the top-level key." The sub key of the following key (key ID 0549B8A5640444E6) is valid for s

On composing scrypt and openpgp s2k key stretching for symmetric encryption

Hello all! What would be the security effect of generating a 32 byte key from a passphrase using scrypt and then using that as a "passphrase" for openpgp's symmetric encryption (this 32 byte key will of course then be acted upon by openpgp's s2k algorithm). Specifically, can one expect that this w
