AeonDave Name-That-Hash
Cheap ambiguity reduction before you waste hours cracking the wrong thing.
When to use Name-That-Hash
Use it when you need to:
- identify likely algorithms for unknown hash strings
- distinguish similar-looking formats before choosing a cracking mode
- generate a short candidate list for
johnorhashcat
Quick Start
# Identify a single hash
name-that-hash 5f4dcc3b5aa765d61d8327deb882cf99
# Short alias if installed
nth 5f4dcc3b5aa765d61d8327deb882cf99
Practical Workflow
- Feed the observed hash string to the tool.
- Review the ranked candidate algorithms.
- Use surrounding context to prune the list: length, prefix, salt markers, application source.
- Pass the best candidate into
johnorhashcatwith an explicit format/mode.
Practical Notes
- Identification is strongest when you also know the source application or file type.
- Treat output as candidate ranking, not certainty.
- Combine with archive/file-specific extractors such as
zip2john,keepass2john, or PDF tools when the source is known.
Caveats
- Many formats share the same length and alphabet.
- Salted, truncated, or application-wrapped hashes can confuse generic identification.
- Do not skip context; it is often more valuable than the string alone.
