In short
AES Text Encryption is a free online tool on inputtesthub.com that encrypts and decrypts text with AES-GCM 256-bit using a password, entirely in your browser. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.
How to use the AES Text Encryption
- Type or paste your input.
- The output is produced instantly as you type.
- Press Copy to take the result with you.
About the AES Text Encryption
The AES Text Encryption encrypts and decrypts text with AES-GCM 256-bit using a password, entirely in your browser. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Encrypting a note before storing it somewhere you do not fully trust.
- Sending a secret through a channel you cannot control.
- Learning how authenticated encryption works.
Details
| Cipher | AES-256-GCM, which provides both confidentiality and tamper detection |
|---|---|
| Key derivation | PBKDF2 with SHA-256 and 250,000 iterations plus a random salt |
| Output | Base64 containing salt, IV and ciphertext — everything needed to decrypt except the password |
Share the password through a different channel from the ciphertext. Sending both in the same email defeats the purpose. And if you lose the password there is no recovery — that is what makes it work.
Frequently asked questions
Is the AES Text Encryption free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Does anything I enter leave my computer?
No. The AES Text Encryption runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the AES Text Encryption used for?
The jobs it is built for: encrypting a note before storing it somewhere you do not fully trust. Sending a secret through a channel you cannot control. Learning how authenticated encryption works. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
Share the password through a different channel from the ciphertext. Sending both in the same email defeats the purpose. And if you lose the password there is no recovery — that is what makes it work.
What are the key numbers for the AES Text Encryption?
Cipher is AES-256-GCM, which provides both confidentiality and tamper detection. Key derivation is PBKDF2 with SHA-256 and 250,000 iterations plus a random salt. Output is Base64 containing salt, IV and ciphertext — everything needed to decrypt except the password. These are printed on the page itself, so you do not have to take them on trust.
Is there an app version?
Yes. The page is responsive and the page works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
