✅Where hashes are used
- File verification: compare a download’s MD5/SHA-256 to confirm it is intact
- Deduplication: use the hash as a content fingerprint to spot identical data
- Signatures & tokens: SHA-256/SHA-512 underpin digital signatures, HMAC and more
💡Tips
- Chinese, Japanese, emoji all work: handled as UTF-8, no garbled text
- Hashing is one-way: it is not encryption, you cannot recover the original text
- MD5/SHA-1 are no longer secure: use SHA-256/SHA-512 for passwords and signatures
A hash function maps input of any length to a fixed-length string; the same input always yields the same result, which is ideal for integrity checks and content fingerprints. This tool computes four common hashes at once.
