A hash has a fixed length, including MD5. There’s no reason to cap password (input) Iength. You can hash the whole bible and still get the same length hash. So either they don’t even hash it, they’re idiots, or they try to be unnecessarily cautious to avoid some other limit / overflow, like POST max size (which would still be counted in at least KB, not several characters). The limit on what special characters you can use is also highly suspicious - that’s not how you deal with injections / escaping your inputs.
