What this does

Hash Generator produces MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from any input text. Useful for verifying file integrity, comparing strings, and security workflows.

When to use it

  • Verifying a download by comparing its SHA-256 to a published checksum
  • Generating an identifier from a string in a deterministic way
  • Quickly comparing two long strings without revealing them
  • Producing a fingerprint of input for caching or deduplication

Frequently asked

Are MD5 and SHA-1 still safe to use?

Not for security — both have known collisions. Use SHA-256 or higher for anything where a malicious party could craft an input.

Is hashing reversible?

No — hash functions are one-way. You can't recover the original input from the hash. (But you can sometimes guess weak inputs by brute force.)
