Hash Generator

// HOW TO USE

1. 01Type or paste any text into the input.
2. 02Toggle the algorithms you want — hashes update live as you type.
3. 03Use the Uppercase toggle to switch the hex output case.

// WHEN TO USE

Use this to generate or verify cryptographic hashes for test data, API request signatures, password reset token checks, or file integrity verification. Hashes are one-way — you can confirm that a given input produces the expected hash but not reverse it. Use it to cross-check which hash algorithm and case format a system uses, to generate expected values for test assertions, and to confirm that two strings differ without comparing them character-by-character.

// WHAT BUGS THIS FINDS

• Wrong hash algorithm chosen

  A system documents SHA-256 but actually uses SHA-1 — generating both hashes for the same input and comparing against the stored value immediately reveals the algorithm mismatch.

• Case sensitivity in hex output

  A signature comparison fails because one system produces uppercase hex and the other lowercase — the Uppercase toggle shows both forms so you can confirm which one the API expects.

• Whitespace or encoding applied before hashing

  Hashing 'Hello' vs 'Hello ' (trailing space) produces completely different digests — the live-update display shows the hash change character-by-character, isolating the unexpected difference.

• Weak algorithm used for security-critical data

  An application uses MD5 for password storage — generating a sample hash confirms the algorithm in use; the test report documents the weak algorithm as a security finding.
