Error Handling

Module Implementation: OpenSSLCryptoInterfaceERR

This module provides the core error detection and handling abstractions. Detectable errors occurring within OpenSSL API calls will produce error objects (instead of raising exceptions). The design choice for error objects is strictly based on maintaining compatibility with older versions of SSL/TLS support. In the future, an optional exception handling mode may be added to this module.

Note: Internal classes are italicized and will only contain a short description.

Errors

OpenSSLFailureToInitializeLibraryError: Specialization of OpenSSLError useful for helping identify native binding issues (independent of API usage errors).

OpenSSLError

This object wraps a specific message digest algorithm. It contains an API for one-shot digests.
