A pretty good content protection (Workshop)

Why should you use Openpgpjs for encrypting all pieces of user content and how to do it correctly, efficiently and sustainably?
Openpgpjs allows browsers to do assymmetric client side encryption with a zero knowledge proof of the private key and this is the only known way for granting the power of the content ownership to whom it really belongs: authors and their audiences, not yourself, the site owner, not the sysadmin and (most importantly) not those dangerous and numerous web programmers.
This workshop covers asymmetric encryption and decryption of content, symmetric encryption and decryption of private keys, RSA keys generation and storage in Drupal, selection of recipients embeded in forms and update of encrypted content.
