WebThe ECDSA implementation contained in this crate has never been independently audited for security! This crate contains a generic implementation of ECDSA which must be instantiated using a separate crate providing a concrete implementation of arithmetic for a particular curve. It’s possible timing variability can exist in concrete curve ... As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits.
