Generate MD5, SHA-1, and SHA-256 hashes from any text. Useful for checksums, password hashing verification, and data integrity checks. Computed entirely in your browser.
A hash is a fixed-length string generated from input data using a mathematical function. The same input always produces the same hash, but you cannot reverse a hash back to the original data.
SHA-256 is recommended for most purposes as it is the most secure. MD5 and SHA-1 are considered weak for security but are still useful for checksums and non-security purposes.
No, all hashing is performed entirely in your browser using the Web Crypto API. Your data never leaves your device.
