CryptPass helps you to store your passwords and many other secrets into an encrypted file, protected by:
- a single master password of your choice
- a sequence of numbers you must keep separately in a safe place (this way, even if someone could access the password file and could discover your master password with social engineering techniques, he will never be able to decrypt your secrets because he can't guess this sequence anyhow)

This way you can store your password wallet within a file anywhere on your file system (including an external SD Card) and then backup it with your favourite cloud storage system, sush as Dropbox and many others.
