Hash & HMAC Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes locally.
Common Use Cases
- Computing cryptographic checksums (SHA-1, SHA-256, SHA-512) for text blocks.
- Generating HMAC tokens for Webhook payload signatures.
- Verifying matching string hashes with a built-in comparison tool.
Tips & Tricks
- Select your algorithm (SHA-256 is recommended for general security).
- Enable HMAC if you need to sign a message using a secret key.
Frequently Asked Questions
Are MD5 and SHA-1 supported?
SHA-1 is supported. MD5 is deprecated and not supported by the browser Web Crypto API, so we stick to secure modern SHA variants.
Is the hash computed secure?
Yes, it uses the native, cryptographically secure browser SubtleCrypto API.
