Work on OS X El Capitan is progressing very well and a first test version will be ready soon. We'll include it in our nightly builds for early testers once available. We would especially like to thank Bruno Bierbaumer for bringing a bug in one of Libmacgpg's subcomponents to our attention which could be abused by a local user to execute shell commands with root privileges (CVE-2014-4677). gpg -output decryptedmessage.txt -decrypt letter.gpg This will create a new file decryptedmessage.txt using the encrypted data from letter.gpg. This security issue has been fixed in GPG Suite 2015.06. #Gpg suite nightly builds updateMost of our users are already running the latest version of GPG Suite, but everyone who hasn't upated to GPG Suite 2015.06 yet, should update to the latest GPG Suite as soon as possible.How to share files securely with GPG suite The computer can read which public key encrypted the data (so I don’t need to specify a KeyID), and it can see it has the private key to that public key in the keyring, so it can use. In every company, files are shared in some kind of way. When customer data is involved this process is becoming security-relevant. GnuPG, also known as GPG, is a command line tool with features for easy integration with other applications. Imagine a CSV file to be shared which is looking similar to this: file includes a lot of private customer data which should not be shared to 3rd-party software. The -armor option tells gpg to create an ASCII file. A wealth of frontend applications and libraries are available. The -r (recipient) option must be followed by the email address of the person you’re sending the file to. The file is created with the same name as the original, but with. GnuPG also provides support for S/MIME and Secure Shell (ssh). In normal cases, this file is then shared on the company internal slack. When not encrypted, then Slack will have access to the file in one way or the other. This can be dangerous and that is why files should be encrypted. There is a solution for this on macOS though which is called GPG suite. Before using the tool we should understand how the techniques used by this program are working. It is an implementation of the OpenPGP protocol which implements the standard RFC4880. This standard is an implementation of private-public-key encryption. The best explanation which I have found is this video: To explain this procedure an own blog article would be needed but there are a lot of resources out there which can be used. It explains the concept quite well and we can see that both of the participants need to have a private key to make the encryption work, but no stress - this will be solved by GPG Suite. ![]() #Gpg suite nightly builds downloadGPG suite setupįirst, you need to download the program on your Mac. #Gpg suite nightly builds how toYou can find the installer on the homepage: #Gpg suite how to download# Screenshot of generating a key pair in GPG SuiteĪfter this, you can find your key in the list. As we have learned in the video we need to share our public key somehow. You can right-click on the key in the program and you have several options to share the key. The easiest is to export it as a file and send it to the other person on Slack. You should never ever share your private key! After sharing your public key with your colleague he needs to follow the same procedure and send you their public key. You can open the document and copy the content and the program will automatically import the public key or you import it by opening GPG suite and press on "Import" on top. ![]() Encrypting filesĪfter both participants have imported the public key of the other person, you can start encrypting the file. Right-click the file and go to Services -> OpenPGP: Encrypt File. ![]() After this select the receiver of the files. The program will then encrypt the files and you will receive a file called like. ![]()
