Smartcards for storing gpg/ssh keys (Linux) - what do I need?
- by Ninefingers
Hi All,
I'm interested in storing my SSH keys and gpg keys on a smartcard for added security. However, I'm a bit uncertain on a few points, which are as follows:
How many keys can I get on a card? I assume both SSH and GPG can store keys on the card.
Is there a limit to key size? I see a lot of cards saying they support 2048-bit keys, what about larger sizes?
Hardware: can anyone recommend a card/reader combination that works well? I've done a fair amount of research and it seems PC/SC readers can be a bit iffy - is this your experience?
Have I missed anything I should be asking? Are there any other hurdles?
I'm aware fsf europe give away cards with membership - I'm not sure I want to join, but... are these cards any good?
