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. 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. The easiest is to export it as a file and send it to the other person on Slack. You can right-click on the key in the program and you have several options to share the key. As we have learned in the video we need to share our public key somehow. Screenshot of generating a key pair in GPG SuiteĪfter this, you can find your key in the list. You can find the installer on the homepage:

Gpg suite from gpgtools download#

GPG suite setupįirst, you need to download the program on your Mac. 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. 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. This standard is an implementation of private-public-key encryption. It is an implementation of the OpenPGP protocol which implements the standard RFC4880. Before using the tool we should understand how the techniques used by this program are working. There is a solution for this on macOS though which is called GPG suite. This can be dangerous and that is why files should be encrypted.

When not encrypted, then Slack will have access to the file in one way or the other. In normal cases, this file is then shared on the company internal slack. 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. When customer data is involved this process is becoming security-relevant. In every company, files are shared in some kind of way. $ gpg -homedir ~/gpg_recovery/.How to share files securely with GPG suite $ gpg -homedir ~/gpg_recovery/.gnupg -list-secret-keys $ cp -r /Volumes//Backups.backupdb//Latest/Macintosh HD/Users//.gnupg ~/gpg_recovery/ gnupg folder out of the Time Machine backup, chown it, and see/extract the private keys as above: $ mkdir ~/gpg_recovery gnupg/trustdb.gpg: Operation not permittedĬopy the. gnupg/tofu.db: Operation not permittedĬhown. The chown will fail with a stream of messages like this: $ sudo chown -R user:staff. Gpg: can't connect to the agent: Permission denied Which means that a chown will fail, and that you can't use the -homedir option with gpg without getting a stream of this: gpg: failed to create temporary file '/Volumes//Backups.backupdb//Latest/Macintosh HD/Users//.gnupg/': Permission denied Time machine backups can be mounted, but they can't be modified in place. You can also directly import them to your new GnuPG keyring instead of storing in an intermediate file (observe the missing -homedir parameter in the GnuPG call after the pipe): gpg -homedir /Volumes//Users//.gnupg -export-secret-keys | gpg -import To list the secret keys available, and gpg -homedir /Volumes//Users//.gnupg -export-secret-keys > secret-keys.gpg To work on the old disk's GnuPG keyring, use the -homedir option, which will result in something like gpg -homedir /Volumes//Users//.gnupg -list-secret-keys As you want to recover the keys from your old disk, connect it to your computer. If GnuPG doesn't work properly afterwards or shows some error message indicating broken permissions, make sure to take ownership afterwards (even if your user name is the same, the internal IDs could be different) by running following command in the Terminal application (it will query for your user password): sudo chown -R $USER:staff ~/.gnupgĪlternatively, you can export your secret keys using the gpg -export-secret-keys >secret-keys.gpgĬommand.

You can simply copy the whole folder to the new machine. By default, the GnuPG keyrings are stored in the (hidden) folder ~/.gnupg with other words the.
