Calculate and verify hashes, checksums, password formats, and SFV manifests locally.
10 of 10 tools
Hash exact text or encoded bytes with modern and legacy digest algorithms, and optionally compare a known digest.
Create securely random, digest-shaped test fixtures in selected algorithm lengths without implying a known original message.
Calculate digests from exact binary file bytes locally, with bounded batches and optional single-file verification.
Calculate named CRC profiles or Adler-32 from exact text or encoded bytes and compare an expected checksum.
Generate, verify, or inspect bcrypt strings locally, with bounded real-computation fixture generation.
Compute precisely identified obsolete NTLM and legacy database password formats for compatibility work.
Hash a digest again with explicit inner and outer algorithms and an explicit intermediate representation.
Generate bounded hexadecimal values with secure browser randomness, including exact odd character lengths.
Create an interoperable UTF-8 SFV manifest from local files using CRC-32/ISO-HDLC.
Verify selected local files against an SFV manifest and report every match, mismatch, missing, duplicate, malformed, and unused entry.
