Additional context

I’m an undergraduate Computer Engineering student at the University of Brasília (UnB), and this contribution is part of a research project involving software security analysis.

I’m happy to adjust the implementation to better match the project’s architecture, coding conventions, or maintainers’ recommendations.

I ran a dynamic analysis tool and observed this error of MessageDigest at runtime: 'expecting one of {SHA-256, SHA-384, SHA-512} but found MD5'. I proposed this change to address the identified cause and prevent the error from occurring again.

This is a false positive. MD5 is used here as a checksum, not as a security control — that's exactly what it's still appropriate for. There's no password, token, or integrity check involved.

Closing this one, but thanks for the effort.
