Frequently asked questions
What is a hash and why would I generate one?
A hash is a fixed-length fingerprint of your data, used to verify file integrity, store passwords securely, deduplicate data and detect tampering.
Which hash algorithm should I choose?
For security-critical uses choose SHA-256 or SHA-512. MD5 and SHA-1 are faster and still common for checksums, but are considered cryptographically broken - avoid them where security matters.
Is my text uploaded to a server?
No. Hashing runs locally with the Web Crypto API and a built-in MD5 implementation. Your data never leaves your device.
