Frequently asked questions

None of these simple hashes should be used for passwords; use dedicated stretching algorithms like bcrypt or Argon2.

No, cryptographic hashing is mathematically a one-way street, though simple words can sometimes be guessed via dictionary attacks.

They are provided strictly for legacy compatibility, such as verifying old file checksums, not for security applications.

Yes, hashing is extremely sensitive. "Hello" and "hello" will produce completely different signatures.

This specific utility processes text strings only; verifying file integrity requires a dedicated file hashing tool.
