An easy way to get started is to combine your email address with two or more passwords.
For example: FirstPassword SecondPassword

Technical Details:
Using client-side JavaScript, your passphrase is run through the memory-intensive scrypt key derivation function (N=218, r=8, p=1, dkLen=32) to generate a secret key. Your secret key is used to encrypt your notepad using AES256 encryption. The ciphertext (encrypted notepad) is sent along with a SHA256 hash of your secret key to the server for storage. To retrieve your notepad, the SHA256 hash is sent to the server, and the ciphertext is returned. The ciphertext is decrypted using your secret key, revealing your notepad. was inspired by the concept of the Bitcoin briainwallet, which allows you to store money in your brain by memorizing a passphrase.
