Yubico Forum

Hi,

I have the following issue: After attaching my yubikey NEO (firmware version: 3.3.6) via USB I can list the card-status.
I have previously successfully written a 2048 bit Authentication and a 2048 bit Signature key to the device. Both keys are shown when I type:
gpg --card-status

But under "Encryption key" it lists: [none]

When I do gpg --edit-key with my master key, select the encryption key (via toggle and "key 1") and then do "keytocard", it gives my only 1 option (Encryption key) which I then select.

After that it tells me the following:
gpg: writing new key
gpg: error writing key to card: not supported

Please support.

EDIT: When using "generate" directly on the key, it generates the A and S keys and also fails when trying to write the E key.
