Generate random hexadecimal strings in the lengths of common hashes — 32 characters like an MD5, 40 like a SHA-1, or 64 like a SHA-256. Handy for seeding test data, mock cache keys, and placeholder identifiers.
Developers often need something that looks like a hash without hashing real input — a fake ETag, a mock commit ID, a placeholder digest in documentation. This tool produces random hex of the right length instantly, in bulk, with copy and export.
Note these are random strings, not hashes of any particular input, so they are for test and placeholder use rather than verifying data.
Frequently asked questions
Are these real hashes of something?
No — they are random hex strings of the same length as those hashes, meant for test data and placeholders, not for verifying real input.
Which length should I pick?
Match whatever your system expects: 32 for MD5-style, 40 for SHA-1-style, 64 for SHA-256-style.
Can I export them?
Yes — copy the set or download it as TXT, CSV, or JSON.
