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
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.
