By default email is insecure, there are many risks to email messages, unauthorized modification or viewing and sender impersonation of a message is something that Governments and crooks carry out on a daily basis.
PGP/GnuPG encryption of emails provides confidentiality and allows for digitally signing a message giving the recipient a method of verifying the identity of the sender as well as making sure the message has not been tampered with.
I was glad to receive a free license from cGeep makers, Safelogic, to review its product and I am so pleased with their software that this is what I intend to use in the foreseeable future to encrypt all of my email messages.
cGeep Pro ships with a plug-in for Outlook Office which offers total integration in the workflow of Outlook Office 2000/XP/2003/2007 users.
One click in Outlook is all you need to encrypt and sign your emails and attachments, making this one of the easiest and most practical email encryption tools.
Through the Manage cGeep Keys window you can import a PGP key pair in .asc format directly and publish or retrieve a public key from any key server.
Encryption of email attachments of any format is possible, using asymmetrical or symmetrical keys with standard AES cryptography but you are not limited to email encryption, you can also use cGeep for file encryption before uploading it directly from cGeep to your FTP server.
This seems like a good feature for backing up sensitive files as it is the integrated file zipping feature.
The Good Stuff
Access to cGeep full source code is available for review, this is the best guarantee you can have against backdoors.
cGeep is based on OpenPGP, a non-proprietary protocol for encrypting email using public key cryptography, this makes cGeep broadly compatible and you can send encrypted files to people who use other OpenPGP software (PGP Corp, GnuPG, Hushmail, etc.)
Encryption can be done dragging a file and dropping it into the cGeep main window. It will also securely wipe files to make its recovery impossible and the software comes with different interchangeable skins/looks.
You can encrypt data and send it directly to an FTP server, you can also configure cGeep Pro to use a proxy for this.
Documentation is complete and comes in the form of a PDF file and tool tips, available in French as well as in English.
The Bad Stuff
There is no Linux or MAC version, cGeep email integration seems to be highly focused on Microsoft Outlook Office, leaving out dozens of other email clients.
Expert users may find cGeep lacks some customization in its options, for example you can not choose where to store the decrypted files and it will always place them in the same folder where the original files resides.
Although the data you upload to your FTP server is already encrypted, it would be good practise to let people use SFTP or FTP over SSL (FTPS), as FTP is a well known unsecure protocol that sends passwords in the clear.
Although not as simple to use, there are free OpenPGP encryption alternatives to cGeep.
cGeep is an excellent uncomplicated way to encrypt all of your emails, if you struggle to understand all the ins and outs of PGP encryption cGeep will guide you through all the process with easy to understand instructions and it specially integrates very well with Microsoft Outlook Office.
The fact that its source code is open to review adds peace of mind to those wary of backdoors.
If you can’t afford cGeep, you can still use some of the free email encryption alternatives mentioned above.
