Wonderful. Worked perfectly, thanks!
var pubKey = '04e6f90994768e51c2834879841542992494b9030e1b765e766f8b60a56213fb9f91903ee24f6baaaaf6afbce3adcfbc4362c1e1e21218ed3f1be6317908db3323';
var signature = 'b32911bfd9f88ae4a0c337df2c0f254d2232a162b85ce3019c2ae7cb1f56f06b525b4813557ace1e6f2f2080e77dd49ecec49d030a4fa23854880e696e941344';
var msg = '...'; // sth secret
var m = signature.match(/([a-f\d]{64})/gi);
signature = {
r: m[0],
s: m[1]
};
var ecdsa = new elliptic.ec('p256');
var res = ecdsa.verify(msg, signature, pubKey, 'hex');
I'll add this to the documentation.
Thanks again!

I'm afraid elliptic does not understand this format. Try splitting signature by halves an pass it as an object:
{ r: '...', s: '...' }
I think it should work this way!
from elliptic.
And if it works - would you mind helping me to fix the documentation to make it more evident?
