Keyboard KeyCode tool

The keyboard KeyCode tool gets keyboard KeyCode values online, retrieves KeyAscii reference values, and extracts keyboard KeyCode and KeyAscii codes online. If the key is a letter, the KeyCode equals the ASCII value of the character's uppercase form; for other characters, the KeyCode equals the ASCII value of the key's upper-shift character. This tool quickly gets the KeyCode and KeyAscii value of every keyboard key online.

How to use

This tool belongs to the “Encryption & encoding” category.

1Pick an algorithm: reversible ones are AES, DES and RC4; one-way digests are MD5 and the SHA family.

2Enter the text plus your key or salt. Encrypting twice with the same key must give the same result.

3Copy the output into your code. When comparing digests, match case and the 16/32-bit variant first.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

Can MD5 be decrypted?

No. MD5 is a one-way digest — you can compare it, never reverse it. So-called "decryption" is a rainbow-table hit.

Why do two runs give different results?

Salts, random IVs, or a different case or source encoding all change the output. Normalise to UTF-8 before comparing.

Is it safe to paste a real key here?

Use it for learning and format checks. Generate and store production keys server-side; never paste a live secret into a web page.
