Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes. Verify hashes and check data integrity.

Verify Hash
MD5: Fast but not cryptographically secure. Use only for checksums.
SHA-1: Deprecated for security. Use SHA-256 or higher.
SHA-256: Recommended for most use cases. Good balance of security and speed.
SHA-512: Higher security, slightly slower. Use for sensitive data.
What is a Hash Generator?
A hash generator converts input data (text, files, or binary) into a fixed-length string of characters called a hash or digest. Hash functions are one-way — you cannot reverse a hash back to the original input. The same input always produces the same hash, but any tiny change in input produces a completely different hash.
Common algorithms include MD5 (128-bit, fast but cryptographically broken), SHA-1 (160-bit, deprecated for security), SHA-256 (256-bit, widely used, recommended for most purposes), and SHA-512 (512-bit, highest security).
Common Use Cases
File Integrity Verification
Generate a SHA-256 hash of a downloaded file and compare it with the publisher's checksum to confirm the file wasn't modified or corrupted.
Password Hashing
Store SHA-256 or SHA-512 hashes of passwords instead of plaintext. Use a salt to prevent rainbow table attacks (bcrypt/Argon2 for production).
Data Deduplication
Hash file contents to detect duplicates without comparing files byte-by-byte. Identical hashes mean identical content.
API Signatures
Use HMAC-SHA256 to sign API requests, ensuring the payload hasn't been tampered with in transit.
