Encrypted email – what you need to know

Encrypted email – what you need to know

Encrypted email can provide the ability to encrypt the main body text and the attachments of an email. There are a number of different standards of encryption methods being used which have been implemented by a range of free and commercial software products.

The sending and receiving of encrypted email will usually require the use of compatible email client software and requires extensive configuration in advance. A wide range of free and proprietary products are available for desktop, laptop and mobile operating systems as well as some specialist webmail providers. Many of these specialist solutions are not generally supported by the majority of online email providers, although there are some browser plug-ins which can provide a certain level of encryption.

Encrypted email uses asymmetric encryption and requires a user to generate a key pair before they will be able to send an encrypted email. Users will also have to exchange public keys before an encrypted email can be sent between them. The private key must be kept secret.

Configuring encrypted email within a corporate environment can be a complicated process, often conflicting with software already installed on to a network and some individuals finding it difficult to install compatible software, generate key pairs, and appreciate the necessity of key management.

Data controllers should have a policy governing encrypted email, including guidelines that enable staff to understand when they should or should not use it. This is becoming an urgent matter due to the impending introduction of the new Data Protection Regulation coming in May 2018.

Frama RMail a solution that makes using encryption easy for both sender and recipient, navigating many of the issue outlined above.
