Expand description

Bind a preferred Digest algorithm to an elliptic curve type.

Generally there is a preferred variety of the SHA-2 family used with ECDSA for a particular elliptic curve.

This trait can be used to specify it, and with it receive a blanket impl of PrehashSignature, used by signature_derive) for the Signature type for a particular elliptic curve.

Associated Types

Preferred digest to use when computing ECDSA signatures for this elliptic curve. This should be a member of the SHA-2 family.
