Despite the appearance of a number of good privacy-focused webmail services, Pretty Good Privacy (PGP) remains the gold standard of email encryption. In this guide, we show you how to use PGP on Mac, explain how it works and how secure PGP really is.

PGP does have a number of issues (discussed below), but it is still the most widely used email encryption system, and therefore the most interoperable with others no matter which platform or email service they use.
It can also be used for signing and encrypting all sorts of other stuff but is mainly used to secure emails.
How does PGP work?
The details of how PGP works are, to be honest, rather complicated. The important thing to remember, however, is that PGP uses public-key cryptography.
Each user has a private key which they keep secret and use to decrypt emails sent to them using their public key. They also have a public key, which they freely so that other people can use it to send them encrypted emails.
- Private key – kept secret and used to decrypt own mail
- Public key – distributed so that others can use it to encrypt mail for sending to you
For this tutorial, we’ll stick to how to use PGP for encrypting emails, but PGP keypairs are also very useful for signing and verifying digital signatures.
PGP vs OpenPGP
When discussing PGP these days we almost always mean OpenPGP. This is an open-source 100% compatible clone of the original PGP, which is now closed-source software owned by Symantec.
Issues with PGP
When PGP is used to secure emails, the metadata - such as email addresses of both the sender and recipient, date and time of sending, and e-mail’s subject line - is not encrypted. Just the body text and any attachments.
https://generousneeds182.weebly.com/key-generation-function-encryption-g-n-k.html. Another problem with PGP is that it does not use Perfect Forward Secrecy (PFS). So once keys for one encrypted email are broken, all other emails encrypted using the same keys will also be compromised.
Arguably the biggest problem with PGP, though, is that it's just not very easy to use, with the result being that most people simply don’t. To combat this, we will show you the two easiest ways to use PGP on your Mac:
Method 1: Malivelope
Mailvelope is a free and open-source browser extension for Chrome and Firefox that makes using PGP on your Mac about as easy as PGP is ever likely to get. Please check out our full Mailvelope How-to guide for a detailed look at how it works.
Method 2: GPGTools with GPG Mail
The most common implementation of OpenPGP is Privacy Guard (also known as GnuPG or just GPG). GPG on its own is a basic command-line tool, but GPGTools for macOS provides a GUI interface and advanced features.
It is worth noting that in 2018 GPGTools make headlines due its vulnerability to the EFAIL attack which affected all versions of PGP at the time. Since GPGTools 2018.2, however, this vulnerability has been patched.
GPGTools is free, but the GPG Mail plugin for Apple Mail is designed to help fund the open-source project and costs $22. This is a one-off fee, but you do need to pay again for new versions as they are released.
Download and install the GPG Suite.
Do please make sure to verify the download before installing it. During installation, stick with all the default settings.Create a new keypair
.Open the GPG Keychain app, select New (the + sign) and fill in the relevant details. You can leave the Advanced options alone or play with them as you please.Upload your public key to a keyserver.
This will allow others to find it using your email address so that they can send you secure PGP-encrypted emails.Do please be aware, though, that once a public key is uploaded to a keyserver it cannot be deleted. The keyserver will send you an email asking you to confirm the upload.You will see your newly created key in the GPG Keychain.If you already have a keypair then you can import it by clicking the Import button. You can then right-click on it -> Send Public Key to Keyserver.Send an encrypted email.
In order to send a PGP-encrypted email, you will need the recipient's public key. If they have already sent it to you (as an email attachment, for example) then you can import it using GPG Keychain.If you already have it, then you can search by email address for public keys that have been uploaded to a key server. Once you have found the key you want, simply import it into your GPG Keychain.Open the Apple Mail app. If you're using an up-to-date version of macOS (10.14 Mojave+), you will need to enable GPG in Mail. To do this, Go to Preferences -> General -> Manage Plug-ins and enable the GPGMailLoader.mailbundle plug-in.Then simply compose an email as normal, ensuring that OpenPGP is selected in the new green drop-down button to the top right of the compose screen.When you have finished writing your message you can sign and/or encrypt it using the two buttons to the right of the Subject line:A) Sign - this verifies that the email was sent by yourself. When GPG Mail is installed, all messages are signed by default (button is blue). Click on the button to turn signing off.B) Encrypt - encrypts the content of the message plus any attachments. It does not encrypt the subject line or hide any other metadata. Click the lock icon (turning it blue) to encrypt your email.Hit Send, and you will be asked for the password to your PGP key. If you are worried that an adversary may gain physical access to your Mac, then you should untick “Save in Keychain.”Receive encrypted messages
When you receive PGP email that has been encrypted and/or signed with your public key, GPG Mail will automatically decrypt it and/or verify the signature using your private key.Verify and sign keys
For maximum security, you should verify and sign keys. You verify a key by comparing the fingerprint you have of the key with the fingerprint owned by the sender to ensure they are identical. Ideally, this is done face-to-face, but a secure communication channel such as Signal Messenger will suffice.Each imported key’s fingerprint is prominently displayed in GPG Keychain.Once you are satisfied with the authenticity of a key, you can sign-it to confirm that you consider it valid. PGP works on a chain of trust, so you can opt to publish your signature in order to help others decide if the key is authentic.And that’s the basic outline of how to use GPGTools to send and receive PGP emails in macOS. GPGTools has more tricks up its sleeve, however, which we may explore in future articles.

When I decided to set up my Mac with PGP encrypted communications, I could not believe how hard it was -- not just to set up the software, but to understand how to use PGP properly. There was no 'PGP for Dummies' tutorial for OS X on the internet. So I decided to write one. This is my über simple, nerd-free tutorial for anyone on Mac. In it, I will:
- Cover exactly how to install and configure PGP on OS X
- Demonstrate how to use PGP in real life
Why this tutorial is the best (ever)
- It works with every app. Unlike other tutorials for PGP, this tutorial does not care what program you use. If you install or uninstall apps, PGP will keep working. If you want to encrypt email, you can use any email program -- Mail.app, Thunderbird, Sparrow, Gmail, Airmail. Or, you can encrypt something besides email, you can do that too. You can write an encrypted letter in Word. You can encrypt a formula in Excel. You can encrypt a URL in Safari. You can encrypt a text with Messages. You can encrypt a bash command in Terminal. It does not matter.
- It is Mac friendly. There is a certain way of doing things on a Mac. If you're not a Mac fan, you won't understand. (That's okay.) Many of the tutorials I found for OS X are not Mac friendly. Many want you to install bloated, Windows-like software; or, install questionable add-ons. I've done the opposite. This PGP tutorial is super Mac friendly. It's PGP, installed the way Steve Jobs would have done it.
- Simple. Above all, this PGP setup is simple. Once you understand how it works, there is nothing you cannot do.
I looked into dozens of ways to set up PGP on my Mac. A lot of them suck for a plurality of reasons. Across the board, this is the best way for 95% of use cases.
Step 1: Install the GPGTools GPG Suite for OS X
This step is simple. Visit the GPGTools website and download the GPG Suite for OS X. Once downloaded, mount the DMG and run the 'Install'.
Inside the installer, you can stick with all default parameters save one exception. On the 'Installation Type' screen, press 'Customize'.
And uncheck the GPGMail package:
Then press 'Install.'
Step 2: Creating your very own PGP key
When the installer completes, a new app called 'GPG Keychain Access' will launch. A small window will pop up immediately and say: 'GPG Keychain Access would like to access your contacts.' Press 'OK.'
As soon as you press 'OK,' a second window will pop up that says 'Generate a new key pair.' Type in your name and your email address. Also, check the box that says 'Upload public key after generation.' Your window should look like this: https://estateskyey979.weebly.com/text-wrap-in-powerpoint-for-mac.html.
Expand the 'Advanced options' section. Incrase the key length to 4096 for extra NSA-proof'edness. Reduce the 'Expiration date' to 1 year from today. Your window should look like this:
Press 'Generate key.'
As soon as you press 'Generate key,' the 'Enter passphrase' window will pop up. Okay, now this is important.
A brief word about your passphrase
The entire PGP encryption will rest on your passphrase. So, first and foremost. don't use a passphrase that other people know! Pick something only you will know, and others can't guess. And once you have a passphrase selected, don't give it to other people.
Second, do not use a password, but rather a passphrase -- a sentence. For example, 'Pennstate55' is less preferable than 'I graduated from Penn State in 1955, ya heard?!' The longer your passphrase, the more secure your key.
Lastly, make sure your passphrase is something you can remember. Since it is long, there is a tendancy you might forget it. Don't. The consequences to that will be dire. Make sure you can remember your passphrase.
Back to Step 2.
Once you decide on your passphrase, type it in the 'Enter passphrase' window. Turn on the 'Show typing' option, so you can be 100% sure that you've typed in your passphrase without any spelling errors. When everything looks good, press 'OK:'
Will be asked to reenter the passphrase. Do it, and press 'OK:'
You will then see a message saying, 'We need to generate a lot of random bytes.' Wait for it to complete:
Et voilà! Your PGP key is ready to use:
Step 3: Set PGP keyboard shortcuts
Next, you will set up four global keyboard shortcuts in OS X.
Open System Preferences, select the 'Keyboard' pane, and go to the 'Shortucts' tab. On the left hand side, select 'Services.' Then, on the right, scroll down to the subsection 'Text' and look for a bunch of entries that start with 'OpenPGP:'
Go through each OpenPGP entry, unchecking each one and deleting the keyboard shortcut:
Next, you will enable and set four shortcuts:
- Enable 'OpenPGP: Decrypt' and set its shortcut to ⌃⌥⌘- (i.e., control option command minus)
- Enable 'OpenPGP: Encrypt' and set its shortcut to ⌃⌥⌘= (i.e., control option command equals)
- Enable 'OpenPGP: Sign' and set its shortcut to ⌃⌥⌘[ (i.e., control option command open bracket)
- Enable 'OpenPGP: Verify' and set its shortcut to ⌃⌥⌘] (i.e., control option command close bracket)
Your keyboard shortcuts should now look like this:
That's it! You're done setting up PGP with OpenGPG on OS X! Now, we will discuss how to use what we set up.
Step 4: How to send a secure email
You can encrypt anything with PGP, but most people will want to encrypt email. So, I will now take a few minutes to explain that. These steps can be transposed for any kind of encryption, from any app on your computer.
To secure an email in PGP, you will sign and encrypt the body of the message. You can just sign or just encrypt, but combining both operations will result in optimum security. Conversely, when you receive a PGP-secured email, you will decrypt and verify it. This is the 'opposite' of signing and encrypting.
Start off by writing your email:
Then, select the entire body of the email and press ⌃⌥⌘[ to sign it:
Next, open the GPG Keychain Access app. Press Command-F and type in the email address of the person you are sending your message to. This will search the public keyserver for your friend's PGP key:
If your friend has more than one key, select his most recent one:
You will receive a confirmation that your friend's key was successfully downloaded. You can press 'Close:'
You will now see your friend's public key in your keychain:
You can now quit GPG Keychain Access and return to writing the email.
Select the entire body of the email (everything, not just the part you wrote) and press ⌃⌥⌘= to encrypt it. A window will pop up, asking you who the recipient is. Select the friend's public key you just downloaded, and press 'OK:'
Your entire message is now encrypted! You can press 'Send' safely.
N.B. You will only need to download your friend's public key once. After that, it will always be available in your keychain until the key expires.
Step 4: How to receive a secure email
With our secure message sent, the recipient will now want to unscramble it. For the sake of this step, I will pretend I am the recipient.
I have recieved the message: Minecraft pixelmon download free mac.
Copy the entire body, from, and including, '-----BEGIN PGP MESSAGE---', to, and including, '-----END PGP MESSAGE---'. Open your favorite text editor, and paste it:
Now select the entire text, and press ⌃⌥⌘- to decrypt the message. You will immediately be prompted for your PGP passphrase. Type it in and press 'OK:'
You will now see the decrypted message!
Next, you can verify the signature. Highlight the entire text, and press ⌃⌥⌘]. Transmission mac shutdown after download torrent. You will see a message confirming the verification:
You can press 'OK.'
What does encrypt, decrypt, sign, and verify mean?
Now that you know how to sign and encrypt outgoing messages, and decrypt and verify incoming ones, let us discuss what these terms mean.
Encrypt takes your secret key and the recipient's public key, and scrambles a message. The scrambled text is secure from prying eyes. The sender always encrypts.
Decrypt takes an encrypted message, combined with the your secret key and the sender's public key, and descrambles it. The recipient always decrypts.
Encrypt and decrypt can be thought of as opposites.
Signing a message lets the recipient know that you (the person with your email address and public key) acutally authored the message. Signing also provides additional cryptographic integrity: it ensures that no one has tampered with the encryption. The sender always signs a message.

Verifying a message is the process of analyzing a signed message, to determine if the signing is true.
Signing and verifying can be thought of as opposites.
When should I sign? When should I encrypt?
It is unnecessary to sign and encrypt every outgoing email. Well, then: when should you sign? And when should you encrypt? And when should you do nothing?
You have three rational choices when you are sending a message:
- Do nothing. If the contents of the email are public (non-confidential), and the recipient does not care whether you or an impostor sent the message, then do nothing. You can send the message as you've sent messages your whole life: in plain text.
- Sign, but don't encrypt. If the contents of the email are public (non-confidential), but the recipient wants assurance that you -- not an impostor -- actually sent the message, then you should sign but not encrypt. Simply follow the tutorial above, skipping over the encryption and decryption steps.
- Sign and encrypt. If the contents of the email are confidential, sign and encrypt. It does not matter whether the recipient wants assurance that you sent the message -- always sign when you encrpt.
I do nothing for 90% of emails I send; security is just not necessary. The remaining 10% of the time, I sign and encrypt. Whenever there is confidential information -- business plans, credit card numbers, bank numbers, social security numbers, corporate strategies, etc. -- I sign and encrypt. I define confidential information loosely, because I'd rather sign and encrypt unnecessarily than do nothing and leak sensitive information. As for the third option, I rarely sign, but do not encrypt. Your profession may warrant radically different usage of PGP.
Why don't you use PGP MIME attachments? Why don't you use the Mail.app PGP plugin?
Some PGP nerds prefer sending PGP with attachments (a.k.a.,
PGP MIME
type), instead of using plain text (a.k.a., PGP INLINE
).Conversely, some PGP
n00bs
want to know why I don't recommend using a PGP plugin for their email client (i.e., the Mail.app PGP plugin).Here's why:
Pgp Download Mac Os X 10.10
- Attachments are a pain in the ass.
- People who use mail plugins for encryption have no idea how they work; the result is a false sense of security.
- Inline text works places where attachments don't (the shell, Facebook, iMessage, etc.).
- The majority of people who have sent me
MIME
test emails using the Mail.app plugins sent undecryptable messages, because they have no idea what they're doing or how it works. - When a plugin generates an attachment and sends it before you can see what is going on, you have no idea what is happening or if it is working.
- Lots of applications and email clients do not have PGP built in, so you need inline anyway.
