Easiest encryption and decryption in Outlook
Encrypt Outlook emails with only one click – also for Office 365
Microsoft Outlook is by far the most widely used email client. A growing number of businesses are using cloud solutions such as Office 365 for their emails. No matter if you operate your own mail server in your own network, use a cloud service or store your emails with providers such as Strato, 1&1 etc., encrypting emails directly in Microsoft Outlook with REDDCRYPT is possible in each case.
Emailing as usual
After installing the REDDCRYPT Outlook plugin you may proceed with writing your emails as usual in Outlook.
You will now find an additional button in Outlook. Upon clicking it you can decide whether to encrypt the Outlook email or not.
Alternatively, you can configure the Outlook plugin to ask you if you would like to encrypt the email before sending, thus, preventing you from accidentally forgetting to encrypt the email.
Encryption with one click
Upon clicking ‘Send’ to send your encrypted email, the Outlook plugin automatically checks whether the recipient already has a REDDCRYPT account.
If there is already a key pair available for the recipient’s email address no further action is needed.The email is automatically encrypted with the recipient’s public key and securely transmitted without anybody being able to intercept the emails’ contents.
If the recipient does not have an account yet, you simply define a passphrase for the first initial email.
Onetime passwords for new recipients
The passphrase you defined has to be communicated to the recipient. We recommend a media break in order to make this process more secure. This means communicating the passphrase to the recipient over a medium that is not email such as SMS, call or letter.
The recipient creates and account with his email address and a password in the REDDCRYPT web app. Upon successful authentication the recipient will be able to see your email and decrypt it when entering the passphrase defined by the sender earlier.
A passphrase is only defined for the first email. Afterwards no passphrase is needed.
Encrypted with one click
When receiving an email – for example as a reply – you will receive an info email in your Microsoft Outlook inbox.
The encrypted email is part of the attachment of a new info mail that describes the REDDCRYPT process. This attachment can be opened and decrypted with the web app, the Windows application or one of our smartphone apps.
Users of the REDDCRYPT Outlook plugin have the additional convenience to encrypt emails with only one click.
Emailing as usual in Outlook
After clicking decrypt you will be able to simply read the email in your Outlook mail client. Of course, you will be able to access attachments if available.
With the REDDCRYPT Outlook plugin you gain the highest user comfort as both encryption and decryption conveniently take place within your email client.
