Open Developer ToolsFrequently Asked Questions
What are hash functions used for?
Hash functions create fixed-length fingerprints of data. Common uses: file integrity checks, password storage, digital signatures, and API authentication.
Is MD5 still safe to use?
MD5 is broken for security purposes (collision attacks exist). Use SHA-256 or SHA-512 for anything security-sensitive.
Is data sent to a server when generating hashes?
No. Hashing runs in your browser using the Web Crypto API. No text is ever uploaded.
