Solutions

1. Ensure the OpenSSL context is initialized before update and not reused after finish.
2. Report the underlying OpenSSL error and retry with a fresh hasher instance.

When it happens

Trigger: Occurs when the OpenSSL-backed hasher fails during a digest update call.

Common situations: Internal OpenSSL errors while streaming data into a hash, e.g. corrupted OpenSSL state.
