Frequently Asked Questions
QWhat is a hash?
A hash function converts any input into a fixed-length string of characters. The same input always produces the same hash; any change in input produces a completely different hash.
QWhich hash algorithm should I use?
Use SHA-256 or SHA-512 for modern applications. SHA-1 and MD5 are cryptographically broken and should only be used for non-security purposes like checksums.
QCan I reverse a hash?
No. Hash functions are one-way — you cannot recover the original input from the hash output. This is by design.
QWhat is MD5 used for?
MD5 is still used for file integrity checks (checksums) and legacy systems, but it's not safe for password storage or digital signatures.
About This Tool
SHA-1, SHA-256, and SHA-512 are computed using the browser's built-in Web Crypto API. MD5 is computed using a pure JavaScript implementation.
