Type Definition ed25519_dalek::SignatureError

type SignatureError = Error;

Errors which may occur while processing signatures and keypairs.

This error may arise due to:

• Being given bytes with a length different to what was expected.

• A problem decompressing r, a curve point, in the Signature, or the curve point for a PublicKey.

• A problem with the format of s, a scalar, in the Signature. This is only raised if the high-bit of the scalar was set. (Scalars must only be constructed from 255-bit integers.)

• Failure of a signature to satisfy the verification equation.
