Yubico Forum

I am trying to reset the OpenPGP applet on my YubiKey Neo, using the instructions here https://developers.yubico.com/ykneo-ope ... pplet.html, because I have ran out of pin retries and can not longer use the pgp features of it. But, whenever I run this line of code:
gpg-connect-agent --hex
scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40
it gives me this error:
ERR 65547 Bad passphrase <Unspecified source>

Am I supposed to supply a passphrase to that command as well. I can not find any documentation regarding it.
Thanks.

--card-status

did you locked the admin pin as well?

I am not sure how to tell if I have locked the admin pin as well or not. But, it kind of appears so from the card-status below.

Application ID ...: D2760001240102000006038129770000

Manufacturer .....: Yubico
Serial number ....: 03812977
Name of cardholder:
Language prefs ...: [not set]
Sex ..............:
URL of public key : -
Login data .......: -
Signature PIN ....: forced
Key attributes ...: 2048R 2048R 2048R
Max. PIN lengths .: 0 0 0
PIN retry counter : 0 0 0
Signature counter : 0
Signature key ....: [none]
Encryption key....: [none]
Authentication key: [none]
General key info..: [none]

The instruction that gives you an error is used to send a wrong PIN in order to lock it, but yours is already locked.

What you want are the two other instructions "scd apdu 00 e6 00 00" and "scd apdu 00 44 00 00".

A.

That worked.
Thanks alot for the help. I was assuming that I had to follow all of the instructions on the page. But, once you said that, it made sense to just do that part.

Okay... So I was receiving the same error as the previous poster:

ERR 65547 Bad passphrase <Unspecified source>

I tried the recommended course of action:

> scd apdu 00 e6 00 00
ERR 65547 Bad passphrase <Unspecified source>
> scd apdu 00 44 00 00
ERR 65547 Bad passphrase <Unspecified source>

So what is to be done when continuing to get an ERR 65547 when attempting to reset the GPG Applet?

Thanks for any help! (oh, and there's currently an open ticket with Yubico)
