Expand description
Errors which may occur while processing signatures and keypairs.
All these errors represent a failed signature when they occur in the context of verifying a signature, including in deserializaing for verification. We expose the distinction among them primarily for debugging purposes.
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 theSignature
, or the curve point for aPublicKey
. -
A problem with the format of
s
, a scalar, in theSignature
. This is only raised if the high-bit of the scalar was set. (Scalars must only be constructed from 255-bit integers.) -
Multi-signature protocol errors
Variants
A signature verification equation failed.
We emphasise that all variants represent a failed signature, not only this one.
Invalid point provided, usually to verify
methods.
Invalid scalar provided, usually to Signature::from_bytes
.
An error in the length of bytes handed to a constructor.
To use this, pass a string specifying the name
of the type
which is returning the error, and the length
in bytes which
its constructor expects.
Fields of BytesLengthError
Signature not marked as schnorrkel, maybe try ed25519 instead.
There is no record of the preceding multi-signautre protocol stage for the specified public key.
Fields of MuSigAbsent
musig_stage: MultiSignatureStage
Identifies the multi-signature protocol stage during which the error occurred.
For this public key, there are either conflicting records for the preceding multi-signautre protocol stage or else duplicate duplicate records for the current stage.
Fields of MuSigInconsistent
musig_stage: MultiSignatureStage
Identifies the multi-signature protocol stage during which the error occurred.
duplicate: bool
Set true if the stage was reached correctly once but this duplicate disagrees.
