Type Definition ed25519_dalek::SignatureError

source · 
pub type SignatureError = Error;
Expand description

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.
