Re: [Jsdsi-users] Exception while creating new KeyPair

Thanks. But what does  jsdsi.Provider.install() actually do ?

Ahhh -- I bet the problem is that you have not installed the Jsdsi
Provider. Try calling jsdsi.Provider.install() in your main.

I'm really not sure -- I did not write these classes and am not
familiar with them. Sean could answer these, but till then, reading
the code is the best plan :)

That said, Signature does indeed override equals() to compare-by-value.

Note sure about KeyPair; perhaps just read the code for equals().
