Problems using SCR335 and gnupgp

2007-05-22 Thread James Davis
I've recently bought a SCR335 card reader and gnupg smartcard. I'm having difficulties getting the card reader working on my Debian 4.0 system with gnupg 1.4.6 I've followed the instructions at http://www.gnupg.org/(en)/howtos/card-howto/en/smartcard-howto.html but running --card-status gives the

Importing backed up card generated key

2007-06-08 Thread James Davis
I've just generated a key pair using my smartcard and asked it to make a backup which it did. I'm doing a practice restore to see how the procedure works and I'm a little stuck. I can import my new public key onto my keyring but when I try to import the secret key it fails to do so and I get the fo

Problems generating keys on card "`SCD WRITEKEY' to agent failed: ec=4.281"

2007-06-19 Thread James Davis
I'm sure I'll get there eventually. I tried generating some new keys on the card today and after it appeared to successfully generate the keys this error came up. Here's part of the output from gpg. "James Davis <[EMAIL PROTECTED]>" Change (N)ame, (C)omment,

Generating an authentication key for smart card

2007-07-09 Thread James Davis
I've been playing with generating keys for transferal to a smart card. This way I can make backups of my keys by exporting them before placing them on the card. Creating 1024-bit RSA keys for signing and encryption is straight forward enough but what do I need to do to generate a (sub?)key to use

Problems with gpg-agent and ssh

2008-10-14 Thread James Davis
After a hard disk died, I recently moved from Debian Etch to Ubuntu Hardy and I'm in the process of rebuilding my gnupg/gnupg-smartcard environment. The card is working fine for encryption and decryption but I'm having some problems getting gpg-agent to use the authentication key for my SSH logins.

A question about verifying keys

2008-12-19 Thread James Davis
A colleague of mine asked me to send him a signed e-mail of fingerprints of some keys that I'd personally verified earlier in the day. I'd also signed the keys, and published the signatures to a public key server. I argued that my signature on the publicly available keys was as good as the signed
