Beware of the key size limitations of OpenPGP smartcards: most of them can only handle 2048-bit RSA keys, a size that is now considered not safe for new RSA key

- mpyne 13y agoWell, 2048 is certainly safe unless your includes direct attention from the NSA itself, where I'd ordinarily tell you that you've already lost. However it looks like Martin is trying to be successful in exactly that scenario so I suppose that's a good tip indeed for this case.

- agwa 13y agoThis is correct. I have a 1.5-year-old OpenPGP card and can attest that all 3 of my keys are 3072-bit.
- fhoxh 13y agoWith version 2.0 of the card and GnuPG 2.0.18, 4096-bit RSA keys are supported: https://wiki.debian.org/Smartcards/OpenPGP#Features https://wiki.debian.org/Smartcards/OpenPGP#Features
