Add support for GnuPG extensions in private subkeys #8

Closed quinot closed 10 years ago

quinot commented 10 years ago

This change adds detection of GnuPG extensions in private/experimental S2K specifiers (type 101), and parsing of gnu-dummy (1001) (indicating absent secret key material), and gnu-divert-to-card (2002) (indicating key material stored on a smartcard).

Example output
