Hashing & Checksums
CTPH hashes Comparator
Compare CTPH hashes and show the differences. Enter the data, choose the digest options, then copy the calculated value.
This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.
CTPH hashes Comparator uses fuzzy-hash comparison for the supplied input. It calls ctph.js similarity and returns a numeric similarity score from 0 to 100.
It calls ctph.js similarity and returns a numeric similarity score from 0 to 100. This result runs in the browser for this catalog category. Processing runs in the browser.
Fuzzy-hash comparison estimates similarity; it does not provide collision-resistant identity or authenticity.
Instructions
- Provide text or data for this tool.
- Retain the generated CTPH strings rather than the original document text. This applies to CTPH hashes Comparator.
- Remove a trailing extra delimiter, which creates a third sample. This applies to CTPH hashes Comparator.
Example
Input: Generate two public samples with the CTPH operation, then place their hashes on separate lines.
Settings: CTPH hashes Comparator: Choose a newline Delimiter for a two-line input. Supply exactly two hashes from the ctph.js-compatible generator.
Result: It calls ctph.js similarity and returns a numeric similarity score from 0 to 100.
Limits
- CTPH hashes Comparator: The CTPH generator and comparator must use compatible formats.
- CTPH hashes Comparator: The score is not a cryptographic identity check or proof of common authorship.
