Frequently Asked Questions
Is my data sent to any server?
No. All hashing happens entirely in your browser using the Web Crypto API. Your input text never leaves your device.
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash (32 hex characters) and is fast but not collision-resistant. SHA-256 produces a 256-bit hash (64 hex characters) and is cryptographically secure, recommended for security-sensitive use cases.
Can I use this to verify file integrity?
Yes. Paste or type the file content to generate its hash, then compare it with the expected hash value to verify integrity.
What is HMAC?
HMAC (Hash-based Message Authentication Code) uses a secret key along with a hash function to produce a keyed hash, useful for verifying both data integrity and authenticity.
