Number of Words

The number of words you want to encrypt. This also determines the number of input boxes that will be provided for you.

Min: 1 Max: 50 Default: 12


If enabled, This ensures that the words you entered are correct by providing another form for you to re-type and verify words.

Default: false

Encryption Method

There are two encryption methods provided: Simple and Complex. All encryption are done in your browser.

Simple Encryption Method

This method is direct and straight to the point. Your data is encrypted using your password directly. This means you can use any AES Decrypter to decrypt your encrypted value without depending on this application.

password = "1234567";
encrypted = AesEncryptFunction(data, password);

Complex Encryption Method.

This method is EXTREMELY SECURE but can only be decrypted using this application because it does not use your password to encrypt data..

Yes! Your password is used to generate a Longer & Stronger Password using a COMPLEX_ENCRYPTION_KEY and Md5 Hashing method.

password = "1234567";
generatedPassword = GeneratePassword(password);
encrypted = AesEncryptFunction(data, generatedPassword);

Show DATE in public data.

If enabled, Date of encryption will be publicly visible in the encrypted document. For best anonymity, this should be turned off.

Default: true

Export Formats

Json Text File

Example of an exported json text file.
