> Hello!
> I'm developing a simple app using QT and Botan. I would like to implement
> "cascaded encryption" using  AES, Twofish and Serpent (like in truecrypt).
> I know that I must create a "Pipe" or "Chain" with three cipher objects.
> The encryption scheme should use a single password for  all the ciphers
> listed.
> How to create keys for these three ciphers from the password in secure
> way??? I know that using single key for multiple encryption algorithms is
> rather insecure... This will be an open-source app.
> Thanks in advance
