Question about getting started with PGP and smart cards

2016-02-26 Thread Joshua Terrill
Hello, I am looking to play around/experiment with gnupg and smart cards. From what little research I've done, I've read about OpenPGP smart cards don't reveal private keys, and do all decrypting/signing on the device itself after entering a PIN. Do I have a correct understanding of this, and if s

Are ZLIB and ZLIB2 no longer supported in GnuPG?

2016-02-26 Thread Anthony Papillion
I recently compiled the latest version of GnuPG 2 from source (.29, I believe) and, when I tried to use it, was told that I had invalid options in my .conf file. Specifically, it told me that ZLIB and ZLIB2 weren't supported as compression algos. Are those two algos no longer supported by GnuPG or

Hello all. Is gnupg-pkcs11 still maintained? Files on sourceforge are from 2011... The idea of using a "standard" key container for GPG keys is appealing, and it could solve my (very personal, I admit, but maybe others feel the same) "problem" with having only 3 keypairs (for example I can't rota
