Hash Generator

Generate secure, irreversible hashes using multiple industry-standard algorithms.

About Hash Generator

A hash reduces any input to a fixed-length fingerprint. The same input always produces the same hash, so hashes are used to verify that a file or string has not changed in transit.

How to use it

  1. Enter the text you want hashed.
  2. Choose an algorithm.
  3. Copy the resulting hash.

Worth knowing

Hashing is not encryption — there is no key and no way to reverse it, but identical inputs always give identical outputs. MD5 and SHA-1 are broken for security purposes and should only be used for non-security checks.

Common questions

Which algorithm should I use?
SHA-256 or stronger for anything security-related. MD5 remains common only for quick integrity checks.
Can a hash be reversed?
Not directly, but short or common inputs are trivially found by lookup, which is why password hashing needs salting and a purpose-built algorithm.
