Elliptic Uses a Cryptographic Primitive with a Risky Implementation

The ECDSA implementation of the Elliptic package generates incorrect signatures if an interim value of 'k' as computed based on step 3.2 of RFC 6979 https://datatracker.ietf.org/doc/html/rfc6979 has leading zeros and is susceptible to cryptanalysis, which can lead to secret key exposure. This...
