Free for Personal, Non-Profit Users and Independent Journalists.
It's an easier to install and use OpenPGP compliant email encryption add-in for Microsoft Office Outlook.
Encryptomatic OpenPGP integrates tightly with the Microsoft Outlook menu system and the Windows desktop to deliver the benefits of OpenPGP e-mail and file encryption, in a manner so that even non-technical users will benefit.
If you have been struggling to implement OpenPGP encryption in Microsoft Outlook and/or Windows, we built Encryptomatic OpenPGP for you. We wanted to use OpenPGP in our business, but discovered that the available software tools were either too expensive, too difficult to deploy, too unsupported, or were too unstable to use reliably. Being software developers, and finding that OpenPGP is a well known open standard, we decided to built the app that we wanted to use. The effort turned proved to be more difficult than we imagined, but we persevered. The result is a highly stable, easy to implement Outlook add-in and Windows desktop encryption app.
End-to-end e-mail encryption is a crucial tool for protecting your business communications and personal privacy. Journalists use OpenPGP to communicate with sources. Businesses are required by law in the U.S. to encrypt certain types of information before sending by e-mail. Lawyers, bankers, and accountants use e-mail encryption to protect their clients. A simple Wizard gets new users up and quickly reaping the benefits of using OpenPGP. Encryptomatic OpenPGP has now been installed on tens of thousands of computers around the world.
After downloading and installing the Encryptomatic OpenPGP add-in, open a new e-mail window in Outlook and locate these buttons in the Outlook tool bar.
Select the "Encrypt" button, compose your message and "Send" your Outlook e-mail Your message will be encrypted then sent to the recipient. Messages can also be signed by selecting the "Sign" button.
When the email message is encrypted, it will be obscured while it is in transit. It will appear to snoops as the message below.
Remember that the recipient will need OpenPGP software to decrypt the message. Fortunately, there are OpenPGP solutions for every platform.
Encryptomatic OpenPGP is available from the Windows right-click context menu. To encrypt or sign a file, a user need only right click on it. Athough Encryptomatic OpenPGP began as an email encryption add-in for Microsoft Outlook users, now it can be used by any Windows user, even if they don't have Outlook.
Encryptomatic OpenPGP uses a highly regarded open source cryptolibrary. We are active contributors to the project, both financially and by offering code improvements and bug fixes. While the crypto library is open source, our signed installer package and our Outlook integration code is presently closed source, but may be opened later when this project is substantially complete.
OpenPGP is an encryption protocol specified in RFC-4880. It is implemented in GPG. OpenPGP is a widely used protocol that changed the world when it was introduced in 1991 by Phil Zimmermann, a person who paid a high personal price to share it with the world. How OpenPGP came to be is a fascinating story.
OpenPGP uses a public key for encrypting a message, and a private key to decrypt. Before sending an encrypted message, you will first need to obtain the recipient's public key. Typical ways of sharing public keys is to just send it to someone in an e-mail, or upload it to a public key server where Encryptomatic OpenPGP can find it automatically. Some enthusiasts even get together to sign public keys in a web of trust.
Encryptomatic OpenPGP for Outlook is hghly compatible with other implementations of OpenPGP including PGP, GPG, and Enigmail.
Yes, it supports sharing, key discovery and revoking keys on popular PGP key servers, such as MIT.EDU. You can add a URL for any other key servers you wish to use. Public keys may also be shared manually or by email.
There are numerous settings in Encryptomatic OpenPGP for Outlook that you may configure, including:
To share your public key by e-mail with someone else, select Encryptomatic OpenPGP's "Key Management" button. Next click on the e-mail address whose public key you want to share. Finally, go to "Key Share" and choose one of the options, such as uploading to a key server, copying to your clip board, saving as a file or sending it in an e-mail
A well managed e-mail server will pass messages to another email server over an encrypted TLS connection. While this is always a good idea, you can't depend on it; whether or not it happens is outside of your control. There are still some email servers accepting unencrypted connections, meaning that your message will be vulnerable to being read or tampered with while in transit. And while TLS encrypts a message while in transit, it doesn't encrypted the message while at rest on an email server. Unencrypted text e-mails remain vulnerable to scanning, tampering, persistent storage and hacking (just ask the people at Sony Pictures).
By using encryption tools like Encryptomatic OpenPGP for Outlook, your message is encrypted end-to-end, from the sender to the receiver. Even if the email server is mismanaged, even if the email message is backed up somewhere, the text of your OpenPGP encrypted email cannot be read or tampered with.
There are several projects we like. Check them out if Encryptomatic OpenPGP isn't the best fit for you.
For email encryption on your Android phone, we like K9 Mail with Open KeyChain. Mozilla Thunderbird has OpenPGP. For day to day mobile messaging, we use and love Signal Private Messenger.
For intercepting encrypted messages, your adversary will likely have more luck seizing your computer or phone than trying to hack open your encrypted email. This is why you should be using whole-disk encryption to protect your computer.
If you are working to improve the world and speaking truth, we want to support your work. Encryptomatic OpenPGP add-in is free for lots of people, and affordable for everyone else.
Remember that while OpenPGP email encryption will protect the content of your email message, it cannot hide the metadata around the message, including the email address you are sending to, the time the message was sent, ip address, the frequency of communication, etc. For most business users, these concerns are less important than obscuring the message content (which OpenPGP does very well). But for journalists and activists, where protecting the identity of a source isparamount, there may be better methods of encrypted communication you should consider using, such as SecureDrop over TOR. Be sure to also take reasonable measures to protect your device, such as whole disk encryption, strong passwords and anti-virus protection.
We will say it clearly: the encryption capabilities and features between the free and business licensed software are identical.
We pay our developers and support people to respond to you. If you value and benefit from our impelementation of OpenPGP, you can help by purchasing a license. Your support encourages us to continue working on the project and to provide daily professional support.
Use of Encryptomatic OpenPGP on a domain that is used to conduct for-profit business requires a business license. No license is required for personal use, or for use by legal not-for-profit organizations, activists and individual journalists. Please play fair so we can continue to serve you.
Encryptomatic OpenPGP works on all Windows versions of Microsoft Outlook that are still supported by Microsoft Corp. It will work with either 32 or 64 bit versions of Outlook. It does not work with Mac, sorry. We love Macs, too, but we haven't had time to retool for Mac development.
Microsoft Office E3 and E4 versions are not supported. There is a conflict with Adobe "Send and Track", disabling it should resolve your issue.
System administrators are able to customize the user interface, removing some features their users might not need. An .msi file supports silent deployment and silent registration. Our installer detects your operating system and installs either the native 64-bit or 32-bit version automatically.
Contact our sales team for enterprise pricing.
Encryptomatic OpenPGP for Outlook is distributed as a code-signed .EXE executable and a .MSI Windows Installer Package. The executable version will check for required Windows components and offer to download and install any that may be missing. In enterprise environments, a .msi distributable file is available. License activation and silent installation can be accomplished by using the command line parameters specified in the help file. An activation free version is available for enterprise site license customers and for use in some shared environment settings.

Safe to Use?
Our Windows Office software products never share information about your email communications, not with us or anyone else. Encryption is done locally, on your PC, and never in the cloud. We do not sell your information or gather details about your email communications, and there is no facility in our software that would allow us to do so. The only communication with our servers is for software update notification and license activation. If you contact us about a problem, our support team may ask you to manually share a log file on your computer so they can assist you, as there is intentionally no automated reporting for this product.
Encryptomatic OpenPGP is capable of integrating with the Windows desktop and the Microsoft Outlook email client.
Encryptomatic OpenPGP Desktop requires Windows 11/10 with latest updates. Encryptomatic OpenPGP Add-on requires Microsoft Outlook 365/2021/2019/2016/2013, 64 bit versions of Outlook. .Net Framework 4.8 or later, 8 GB RAM, 2 GB free disk space, and 2 GHz processor.

OpenPGPis a descriptive term used to describe a published open source specification,, and is in common every day use.
Known IssuesIf you experience a problem using Encryptomatic OpenPGP, it will almost certainly be due to other software add-ins attempting to insert trackers into your emails after they have been encrypted. If you use add-ins like Adobe Send & Track, Hubspot and others, you will very likely encounter problems. They want to track your emails, and they do this by inserting tracking code into your emails on the Outlook Send event. This breaks OpenPGP signing and is the very definition of a 'man in the middle' attack. Consider strongly whether the benefit you receive by using such intrusive add-ins are really worth your privacy. At worst, these add-ins prevent Encryptomatic OpenPGP from working; at best, they break signing and may cause the recipient to see a warning that the message has been tampered with (which is true).
That said: if you find a bug that is not related to the above, please contact us immediately. We issue regular updates to Encryptomatic OpenPGP and will include a fix in the next release.
