Online Hash Generator Tools
Generate cryptographic hashes from text or files in your browser. Choose from MD5, SHA-1, SHA-256, SHA-512, HMAC, and more — all computed locally with no data sent to any server.
All hashing runs 100% in your browser using the Web Crypto API. No login required, no data uploaded.
MD5 Hash Generator
Generate MD5 hashes from text or files. Note: MD5 is not cryptographically secure.
SHA1 Hash Generator
Generate SHA-1 hashes from any text. Note: SHA-1 is deprecated for security use.
SHA256 Hash Generator
Generate secure SHA-256 hashes from any text using the Web Crypto API.
SHA512 Hash Generator
Generate secure SHA-512 hashes from any text using the Web Crypto API.
HMAC Generator
Generate HMAC authentication codes using SHA-256 or SHA-512 with a secret key.
Hash Compare Tool
Compare two hash values to verify integrity or check if passwords match.
File Checksum Generator
Generate SHA-256, SHA-512, or SHA-1 checksums for any file to verify integrity.
Choosing the right hash algorithm
- MD5 — fast 128-bit hash, used for checksums and non-security fingerprinting. Not suitable for passwords.
- SHA-1 — 160-bit hash, deprecated for security use. Still used in Git commit IDs.
- SHA-256 — 256-bit secure hash. Standard for digital signatures, certificates, and blockchain. Recommended.
- SHA-512 — 512-bit variant of SHA-2. Stronger and faster on 64-bit systems.
- HMAC — keyed hash for message authentication. Used in webhook verification and API request signing.
- File checksum — verify file integrity after download by comparing hash values.
