FAQ

No. Hash functions are one-way operations designed to be irreversible.

SHA-1 and SHA-256 use the Web Crypto API. MD5 is generated with a lightweight JavaScript implementation for quick checksum tests.

You can hash strings of several megabytes. Extremely large inputs may be limited by browser memory.
