How to use Triple DES
Get the best out of Triple DES: every option explained, a worked example, and what to check when the output is not what you expected.
Updated July 31, 2026
What it does
Encrypt or decrypt legacy payloads using Triple DES locally in the browser. It runs entirely in your browser — your input never leaves your device.
Options
Every setting this tool exposes, straight from the code that validates it.
| Option | Type | Default | What it does |
|---|---|---|---|
text | text | — | Text to encrypt, or ciphertext to decrypt. Required. |
key | text | — | 3DES key. Accepts at least 1 characters. Required. |
mode | one of: encrypt, decrypt | encrypt | Defaults to encrypt. |
Worked example
Run these settings on the tool page:
text:hellokey:my-secretmode:encrypt
You get:
U2FsdGVkX1+9F4GERyZsKrHzaOH6jyZb
Getting the result you want
Most of the control here is in the options above. If the output is not what you expected, the setting to check first is mode — those change the shape of the output rather than the input it accepts.
Troubleshooting
- Nothing happens / the output stays empty.
text,keyare required — the tool waits until you provide them. - A value is rejected.
keyaccepts at least 1 characters. Anything outside that is refused rather than silently clamped. - It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.
Automating it
The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.
Bashcurl "https://api.toolsxpo.com/v1/triple-des" \ -H "Authorization: Bearer $TOOLSXPO_KEY"
It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
