Overview

elliptic is a Fast elliptic-curve cryptography in a plain javascript implementation.

Affected versions of this package are vulnerable to Timing Attack. Practical recovery of the long-term private key generated by the library is possible under certain conditions. Leakage of bit-length of a scalar during scalar multiplication is possible on an elliptic curve which might allow practical recovery of the long-term private key.
