Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes with hex or Base64 output. Use this free online tool directly in your browser.
Input Text
What is Hash Generator?
Cryptographic hash functions take arbitrary input and produce a fixed-length digest that acts as a fingerprint of the original data. The same input always produces the same hash, and even a single character change produces a completely different hash. MD5 and SHA-1 are legacy algorithms — fast but cryptographically broken, suitable only for checksums and non-security purposes. SHA-256 and SHA-512 are current standards used in digital signatures, TLS certificates, password hashing (via PBKDF2 or bcrypt wrappers), and blockchain protocols. This tool generates hashes instantly in the browser with no server round-trip, making it safe for sensitive strings. Note: for password storage, use a purpose-built algorithm like bcrypt, scrypt, or Argon2 — raw SHA hashes are not suitable for passwords due to their speed.
How to use
- 1
Paste or enter your data in the Hash Generator input area.
- 2
Run the conversion, generation, or validation action.
- 3
Copy or download the result for your project workflow.
Common Use Cases
- 1
Generate a SHA-256 checksum to verify a downloaded file has not been tampered with
- 2
Produce a deterministic identifier from a string (e.g., hashing an email for use as an avatar seed)
- 3
Generate MD5 hashes for legacy systems or cache keys where cryptographic strength is not required
- 4
Verify that two separate strings produce different hashes to confirm hash function behavior
- 5
Test HMAC-style workflows by comparing manually generated hashes against expected values

Frequently Asked Questions
What is Hash Generator?
Hash Generator is a free browser-based utility on Bite Size Tools. Generate MD5, SHA-1, SHA-256, and SHA-512 hashes with hex or Base64 output.
Is Hash Generator safe to use with sensitive data?
Yes. Tool processing runs in your browser, so your input is not sent to a server by default in this app.
Can I use Hash Generator for production work?
Yes. You can use the output directly in development and production workflows after validating it with your project requirements.
