FAQ
- Which algorithms are available?
- MD5 (legacy, 128-bit), SHA-1 (legacy, 160-bit), and the SHA-2 family (224/256/384/512-bit). All algorithms use the Web Crypto API or fast pure-JS implementations.
- What happened to BLAKE3?
- BLAKE3 was removed when the tool moved from WebAssembly to the Web Crypto API. If you need BLAKE3 hashing, consider using a dedicated tool.
- What is a hash used for?
- Verifying file integrity, comparing data without revealing the content, and generating unique identifiers for strings.
- Is my data uploaded anywhere?
- No. All hashing happens locally in your browser.
