How to use this tool
- Enter text or upload file to hash
- Select hash algorithm (MD5, SHA-1, SHA-256, SHA-512)
- Click Generate to create hash
- Copy resulting hash for comparison or storage
- Use for file integrity checks, password hashing (with salt), or checksum verification
About MD5 / SHA Hash
Cryptographic hash functions create fixed-size "fingerprints" of data. Same input always produces same hash; any change produces completely different hash. Hashes are one-way, you cannot reverse them to get original data.
Use cases: verify file integrity (compare downloaded file hash to published hash), detect tampering, create checksums, hash passwords (with proper salting), generate unique identifiers from content.
All hashing uses browser's Web Crypto API (SubtleCrypto). Your data never uploads, critical for hashing sensitive files, documents, or passwords. Results are identical to command-line tools (md5sum, shasum).
Frequently asked questions
SHA-256 for modern applications (security, integrity). SHA-512 for even stronger security. MD5 and SHA-1 are legacy, cryptographically broken, avoid for security purposes but okay for non-security checksums.
No. Hash functions are one-way by design. You cannot decrypt or reverse a hash. This makes them ideal for password storage (store hashes, not passwords) and integrity verification.
Hash functions are deterministic: same input always produces same output. This property enables integrity verification, if file hash matches expected hash, file is identical to original.
