🔐 What
is this application?
This is a text encryption tool that
allows you to protect your messages using a secret seed (password). Only someone with the
correct seed can decrypt your message.
🌱
What is a seed?
A seed is like a secret password
that you choose. It's used to generate a unique encryption key. Important: You must
remember your seed to decrypt messages later. Without it, you cannot recover the
original text.
🔒
What does "Encrypt" mean?
Encrypting is the process of
transforming readable text into an encoded format that appears as random characters. This
protects your information so only someone with your seed can read it.
Example:
Original: Hello World
Encrypted: SGVsbG8gV29ybGQ=
🔑
What does "Decrypt" mean?
Decrypting is the reverse
process: it takes the encrypted text and converts it back to the original readable format
using the correct seed.
💡
What is it used for?
- Protect confidential messages before sending them
- Store sensitive information securely
- Share passwords or private data safely
- Create encrypted notes for personal use
📝 How to
use it?
- Choose a seed: Enter a secret word or phrase
- Write your text: Type the message you want to protect
- Click "Encrypt": Your text will be converted to an encrypted format
- Copy or download: Save the encrypted result
- To decrypt: Paste the encrypted text, enter the same seed, and click
"Decrypt"
⚠️
Security Note
Your text is
encrypted with AES-GCM, a 256-bit cipher the browser provides, and the key is derived from
your seed with PBKDF2 and 310,000 rounds, which is what makes a guessable seed slow to
attack. Nothing is uploaded: the encryption happens on this page.
Two things
this still does not do. It cannot protect you from someone who has the device open, because
the text and the seed are both in this page. And it cannot encrypt for a specific
recipient, the way a message key does, because there is no server and no public key: the
same seed has to encrypt and decrypt. Never share your seed with anyone unless you want them
to read your messages.
