What the AES Encrypt / Decrypt does
AES Encrypt / Decrypt: transforms Status and Result from Action, Text (plain text to encrypt, or the encrypted bundle to decrypt) and Password.
The inputs are Action, Text (plain text to encrypt, or the encrypted bundle to decrypt) and Password; the output is Status and Result. Set your values, then run the tool to see the result.
Most people who open the AES Encrypt / Decrypt are anyone replacing a weak password. A secret that travels to a third-party server is no longer entirely a secret.
Generated secrets never touch the network. They are produced in your browser and stay there.
The field reference, the method and a worked example using the default inputs follow the tool itself.
What do the AES Encrypt / Decrypt fields mean?
The AES Encrypt / Decrypt uses 3 inputs. The page opens in a usable state: real values in, real answer out, ready to edit.
| Field | What to enter | Default |
|---|---|---|
| Action | choose from Encrypt or Decrypt | Encrypt |
| Text (plain text to encrypt, or the encrypted bundle to decrypt) | paste or type any amount of text | Meet at the usual place at 9. |
| Password | required | correct horse battery staple |
How does the AES Encrypt / Decrypt work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same transformation.
Validation runs before the calculation, which is why a mistyped value shows an error rather than a plausible-looking result.
What a typical run looks like
You provide: Action, Text (plain text to encrypt, or the encrypted bundle to decrypt) and Password
What happens: the file is read into memory by your browser, processed locally, and offered back as a download. It is never uploaded.
You get back: the output file, and a status line reporting what the tool read and wrote.
A fast machine finishes sooner than a slow one, and the only ceiling on file size is the memory available to the page.
How to use it
- Pick a value for Action: the options are Encrypt or Decrypt.
- Paste your content into Text (plain text to encrypt, or the encrypted bundle to decrypt).
- Type Password.
- Press Run.
- Read Status and Result in the results panel.
- Copy Link when you want to return to this exact configuration; Print when someone needs it on paper.
What this tool does not do
- Anything generated here is only as safe as wherever you store it afterwards.
- Randomness comes from your browser cryptographic source, which is suitable for real secrets.
- It will not warn you that a different tool would suit your question better.
Frequently asked questions
Action, Text (plain text to encrypt, or the encrypted bundle to decrypt) and Password. That is the whole form. Every box already holds a working value, so you can change one value at a time and watch how the result responds.
No. There is no upload step, no database, and nothing to delete afterwards.
No charge. Everything on the page is available without signing in.
It follows the standard definition for this operation, so the result matches what a reference implementation would give.
