Re: [Q?] How to generate keys with "vv" prefix on command li

Hello,

Just a note of caution: you might open up to replay attacks by having your keys valid for two different sets of validation servers.

To generate vv tokens with ykksm-gen-key use a start of 280375465082880 (0xff0000000000) or higher

[S] How to generate keys with "vv" prefix on command line?

2014-11-10T22:23:03+01:00

I'm generating my own keys for the NEO tokens, that will work with the authentication backend I've built. The user account administration tools I wrote use command-line utilities such as ykksm-gen-keys, etc.

The problem is, ykksm-gen-keys only seems to generate keys that begin with the "cc" prefix, and those prefixes cannot be uploaded to Yubico. Only "vv" prefixes can be uploaded.

The only solution I've seen is to use the Personalization Tool, but that's not command-line, it's a GUI.

Any ideas? Thank you.
