Error when using an encrypted private key

[Jason Cooper]

I'm using Linux Mint 12, which comes with GnuTLS 2.10.5. I'm working on configuring Git with https. On Linux Mint, Git is using GnuTLS under the hood, so I'm hoping this is the right place to get help.

Basically, what I'm seeing is that my requests never get to the server when I use an encrypted private key. I started using gnutls-cli to debug and this is what I'm seeing:

$ gnutls-cli -V --x509certfile usercert.pem --x509keyfile userkey.pem titan.cloud.company.com

Processed 1 client certificates...

*** Error loading key file: ASN1 parser: Error in TAG.

If I use an unencrypted private key, then the connection is successfully made:

$ gnutls-cli -V --x509certfile usercert.pem --x509keyfile userkey2.pem titan.cloud.company.com

Processed 1 client certificates...

Processed 1 client X.509 certificates...

Resolving 'titan.cloud.company.com'...

Connecting to '192.169.2.1:443'...

....

What I'm really wondering is can I use encrypted keys with GnuTLS 2.10.5? If so, any hints on what else could be the problem? I'd really prefer to not have my private key stored in the clear.

Thanks for the help,

Jason
