pub struct Error { /* private fields */ }
Expand description

Signature errors.

This type is deliberately opaque as to avoid sidechannel leakage which could potentially be used recover signing private keys or forge signatures (e.g. BB’06).

When the std feature is enabled, it impls [std::error::Error] and supports an optional [std::error::Error::source], which can be used by things like remote signers (e.g. HSM, KMS) to report I/O or auth errors.

Implementations

Create a new error with no associated source

Create a new error with an associated source.

NOTE: The “source” should NOT be used to propagate cryptographic errors e.g. signature parsing or verification errors. The intended use cases are for propagating errors related to external signers, e.g. communication/authentication errors with HSMs, KMS, etc.
