Encryption
Basic information about encryption.
Encryption means scrambling electronic information into a secret code of letters, numbers and symbols. Encrypted information can't be unscrambled without a decoding key.
Encryption is widely used in the public and private sector to protect sensitive electronic data. For example, it’s used to protect credit card information when you purchase something on the Internet.
Many people also choose to use readily available encryption programmes to encrypt their email, files, folders, documents and pictures. These same technologies are also used by terrorists, criminals and paedophiles to conceal their activities.

Implementing RIPA Part III powers
The increased availability of encryption software means investigators are already encountering more cases of protected data. It is, therefore, timely to implement the provisions covered in Part III of the Regulation of Investigatory Powers Act that require:
- protected electronic information to be put into an intelligible form
- that the key is disclosed, to enable the data to be put into an intelligible form
Code of practice
Parliament has now approved the code of practice for the investigation of protected electronic information. It came into force on 1st October 2007.
It provides guidance for authorities to follow when they require disclosure of protected electronic information.
