MDC was introduced in 2001 and is enabled by default for new keys in GnuPG since 2003. However, old keys that use old algorithms don't automatically benefit from MDC. Part of the mitigations against the Efail vulnerability ( ), are that messages with no integrity check are no longer decrypted. Those mitigations were published with GPG Suite 2018.2 for macOS 10.13 High Sierra and 2018.3 for macOS 10.12 Sierra. Now if we received a file that is encrypted by our Public Keys we need to decrypt it with our Private Key.

Since more users than we anticipated rely on messages or files using no MDC, we added options in GPGServices and GPGMail to still decrypt such messages or files. We can also optionally specify the output file with -output option like below. We do not recommend this, since without integrity protection (missing modification detection code) it is not possible to determine whether or not the encrypted data has been modified. Decrypting legacy messages or files with no MDC So only use the workarounds, if you are absolutely certain that the message or file has not been modified. GPG Suite 2018.3 added the ability to decrypt messages and files, which have no integrity protection, in GPGServices and GPGMail. They are not at all meant to be longterm solutions but merely a workaround to access old messages on which you rely. We strongly suggest to not use the workarounds with newly received messages. GPGServices displays a warning for messages or files that do not have an integrity check. Only continue if you know what you are doing and are certain the message or file has not been modified. To decrypt files in GPGServices right-click the file and select Services > OpenPGP: Decrypt File. To decrypt messages in GPGServices mark the OpenPGP message, right-click and select Services > OpenPGP: Decrypt Selection. Since Efail is foremost a method to exfiltrate decrypted content from a specially crafted email, we would like to know more if you encounter a missing or modified MDC error with in one of your emails. (With gpg -debug help showing available choices to give after -debug.) gpg -debug-all -vvv hello.gpg Passphrase on the command line. Please get in touch with us via System Preferences > GPG Suite Preferences. The private key, which is protected by a passphrase, is handled by gpg-agent. This means that with GnuPG 2.1 adding -passphrase on the command line will no longer work out of the box. We will also provide you with a workaround for GPGMail if necessary.

The causes for messages with no MDC can be various.

Using a wrong key configuration, outdated software or old legacy keys with weak security can all result in messages lacking an integrity check. In case you are using a very old key with weak security, we recommend transitioning to a new key.

With its effortless operation and thorough setup, GPG Suite for Mac represents a solid solution for encrypting e-mail.When you think your key is not at fault, please ask the message author of the problematic message about the software and version they are using and send us a report via System Preferences > GPG Suite Preferences.

Its ability to work with the Mac Mail application, seamlessly, is an advantage over other programs.

GPG Suite for Mac's wizard walks the user through the initial steps to set up encryption. Users must designate e-mail addresses and enter a passphrase for use. It's a small touch, but we liked that the program warns you if your passphrase is weak. While creating a new e-mail in the Mail application, the user sees additional icons for encrypting and signing the e-mail. Note that you can't encrypt a message until the recipient is added, but this doesn't reduce the program's functionality. GPG Suite for Mac allows you to export a key phrase pair, allowing someone on the other end to decrypt the message by entering it. From the setup menu, which is well designed, users can select buttons on the top for importing and exporting phrases, as well as creating new ones. The main part of the window displays a listing of created keys, along with the associated e-mail, date created, and a short identification code.įor those users who want a basic and easy way to encrypt e-mails, GPG Suite for Mac fits the bill and performs well. GPG Suite is open source software bringing OpenPGP to Apple macOS. The project originated from efforts to revamp GPG Mail development in 2010. The personal privacy is one of the most underestimated goods everyone of us has. By encrypting your data before sending them over the internet you prevent others from reading them during the delivery process.
