Re: [Jsdsi-users] KeyPairs generated by other APIs ==> Exception

[Somaya A. <som...@ya...>]

Hi Sameer,

Yes i can, but, for you to run it you'll need to
install the Agents framework that i'm using (JADE
multiagent framework). This is becoz, I'm using
keypairs generated by this API. Do u have time to do
this?!

Thanks,
Somaya
