Using PGP email with Gmail can be a bit tricky, but don't worry, it's definitely doable.

First, you'll need to enable two-factor authentication in your Gmail account to add an extra layer of security. This will help protect your account from unauthorized access.

Next, you'll need to generate a PGP key pair, which consists of a public key and a private key. The public key will be used to encrypt messages, while the private key will be used to decrypt them.

To generate a PGP key pair, you can use a tool like GnuPG. This will give you a unique key pair that you can use to encrypt and decrypt messages.

Setting Up PGP Email

Setting up PGP email encryption on Gmail requires some tinkering, but it's worth the effort. You'll need to install an extension to get started.

Gmail isn't set up to encrypt messages with PGP out of the box, so you'll need to take matters into your own hands. Two popular extension choices are Mailvelope and FlowCrypt.

Mailvelope and FlowCrypt can help you encrypt your emails, but you'll need to follow the instructions carefully to set them up correctly. This includes installing the extensions and configuring them to work with your Gmail account.

Gpg4win is an alternative option for setting up PGP encryption, but it requires a standalone email client rather than a browser-based solution. This might be a better option depending on your specific security needs.

Security and Protection

Mailvelope provides proven security, as validated by audits and the open source community. It offers full end-to-end encryption, meaning only the sender and recipient can read the email content. This is achieved through PGP on client-side only, ensuring that Google servers cannot access or read the content.

Mailvelope's security features include encryption of attachments, encryption in transit (TLS), and encryption at rest. This means that even if your email account is hijacked, encrypted emails remain unreadable to the attacker. Additionally, Mailvelope helps protect you from phishing by identifying signature mismatches in emails.

Here are some key security features of Mailvelope compared to Gmail:

By using Mailvelope, you can rest assured that your emails are secure and protected from unauthorized access.

Phishing Detection

Phishing detection is a crucial aspect of online security. Mailvelope helps protect you from phishing by identifying signature mismatches in emails.

This feature can be a lifesaver, as phishing scams often rely on tricking users into revealing sensitive information. With Mailvelope's phishing detection, you can rest assured that your emails are being thoroughly checked for potential threats.

By identifying signature mismatches, Mailvelope can alert you to potential phishing attempts, giving you time to react and protect your sensitive information.

Security Audits

Security audits are a crucial aspect of ensuring the security of your email communications. Mailvelope provides proven security, as validated by audits and the open source community.

Mailvelope's security features are transparent and auditable, allowing users to have confidence in the security of their emails. The code is fully open-source and independently audited, giving users a clear view of what's going on behind the scenes.

As you can see from this comparison, Mailvelope offers significantly stronger security features than Gmail. By using Mailvelope, you can rest assured that your emails are protected from unauthorized access and tampering.

Create a strong password

Creating a strong password is crucial to secure your communications, and it's recommended to follow the advice from the How to install Mailvelope & send a PGP encrypted message with Gmail section.

A strong password should be entered when setting up PGP, as taking all the effort to set it up could be in vain if it's not.

For advice on how to make a strong password, see the How to install Mailvelope & send a PGP encrypted message with Gmail section above.

It's worth noting that a strong password is essential for protecting your messages, especially when sending PGP encrypted emails.

FlowCrypt will look for your public key for you when you enter your desired recipient's address in the add recipient field, but this requires a strong password to be set up first.

This means that if you don't already have a PGP key pair, you will be asked by FlowCrypt to protect the message with a one-time password, which highlights the importance of having a strong password.

Key Management

Managing your PGP key is crucial for secure email communication. You can manage a single key for organization-wide encryption and decryption.

To generate a key, you'll need to enter your full name and Gmail address, along with a secure password, when setting up Mailvelope. This is because the password will be used to protect your encrypted mail.

For Firefox, the process of setting up Mailvelope involves clicking on the lock icon in the corner to bring up a menu and begin the configuration.

You'll have two options: Generate Key or Import key. Choose the first option to create a new key.

A secure password is essential to protect your encrypted mail. You should choose a password that's difficult to crack.

To add your public PGP key to your mailbox, go to your dashboard, then Mailboxes, and click on the mailbox you want to add the key to. Enable "Pretty Good Privacy (PGP)" and copy/paste your public PGP key.

Remember to click Save after adding your public PGP key.

Mailvelope and FlowCrypt are two popular browser add-ons that bring PGP encryption to your webmail service. Mailvelope is an open-source browser add-on that's been around for over a decade and can be used with Firefox, Chrome, and Edge.

Mailvelope enables users to both encrypt messages through their webmail and receive encrypted emails from other types of software. It can be used with a number of webmail providers including Gmail, Outlook, and Yahoo.

Setting up Mailvelope can be a little technical, but it's not the easiest to operate. In contrast, FlowCrypt is even easier to set up and send emails. With FlowCrypt, you can install the extension by clicking on the big green GetFirefox Extension button on the FlowCrypt site.

Here are the basic steps to set up FlowCrypt:

  1. Click on the FlowCrypt symbol in the corner
  2. Use the Google sign in

  4. Give FlowCrypt the permission to manage, read and send emails
  5. Create a new key
  6. Choose a strong passphrase that you do not use elsewhere, and click Create and Save
  7. I DO NOT advise you to write down your password using pen and paper. Please memorize the password or use a password manager like KeePass. Check the box and click Ok
  8. And you are DONE! Login to your Gmail account to compose an email.

To send an encrypted email with FlowCrypt, you'll need to click on the COMPOSE ENCRYPTED EMAIL button, which will take you to the next step.

Mailvelope is an open-source browser add-on that's been around for over a decade. It's one of the most popular PGP options and can be used with Firefox, Chrome, and Edge.

Mailvelope enables users to both encrypt messages through their webmail and receive encrypted emails from other types of software. It can be used with a number of webmail providers including Gmail, Outlook, and Yahoo.

Despite its popularity, Mailvelope is not necessarily the easiest to operate. Many users report that the setup can be a little technical and that it isn't the most intuitive program.

To install Mailvelope, you'll need to head to its homepage, download the add-on, and click on the Add button. You'll then be brought to a setup page where you'll need to enter your full name and Gmail address, as well as a password.

Mailvelope provides proven security, as validated by audits and the open source community. Here are some of its security features:

Overall, Mailvelope is a secure option for encrypting your emails, but it may require some technical setup.

Hide Email Subject

If you're using PGP, it's a good idea to hide your email subject for added protection.

PGP doesn't encrypt the email subject, which can be a security risk if it contains sensitive information.

You can customize the email subject to be replaced with "Encrypted Email", or choose a different option that suits your needs.

Gmail and Webmail

Gmail is a popular webmail service that offers end-to-end encryption through PGP.

Gmail's web interface allows users to compose and send encrypted emails using PGP.

Gmail's encryption is enabled by default for all emails, but users can also manually enable PGP encryption for specific emails or conversations.

PGP encryption in Gmail uses a public key to encrypt the email and a private key to decrypt it.

Why Use Gmail?

Gmail is a great option for those who value their online security. Most emails are sent as plaintext and can be intercepted, read, and altered.

For sensitive or valuable information, normal email isn't suitable.

Google has been working to make its services more appealing to business users who care about privacy.

Gmail has added end-to-end encryption (E2EE) to its web service for Google Workspace Enterprise Plus users.

This allows paying users to send and receive encrypted emails, with the email header remaining unencrypted.

Gmail E2EE beta is not yet available to users with personal Google Accounts.

Webmail vs Email Clients

Webmail and email clients are both options for managing your emails, but they have some key differences. One downside to webmail is that it's browser-based, making it susceptible to the security weaknesses of your browser.

Using a standalone email client like GPG can be a better option for those who prioritize security. This is because standalone email clients are less vulnerable to browser security issues.

Browser-based webmail services like Gmail are convenient and accessible from anywhere, but they may not be the best choice for those who need extra security measures. Depending on your threat model, a standalone email client might be a better fit.

If you're concerned about security, you may want to consider using a standalone email client like GPG, which is designed to provide an additional layer of protection.

If your mailbox doesn't support PGP encryption, which is the case with Gmail, Hotmail, and YahooMail, you'll need to create a PGP key pair to encrypt your emails.

You'll only need to add your public PGP key to SimpleLogin, not your private key, so don't worry about keeping that secure.

To create a PGP key pair, you'll need to follow the instructions on SimpleLogin, which is a straightforward process.

Once you have your public PGP key, you can add it to your mailbox on SimpleLogin by following these steps:

  1. From your dashboard, go to Mailboxes
  2. Click on the mailbox you would like to add your public PGP key to, and click Edit →
  3. Enable “Pretty Good Privacy (PGP)” and copy/paste your public PGP key
  4. Click Save

That's it! From now on, all emails forwarded by SimpleLogin alias will be encrypted with your key.

Business and Suitability

Using PGP encryption with Gmail may not be the best idea from a privacy standpoint, as Google still gets access to your metadata even if your emails are encrypted.

If you have serious privacy concerns, it's best to switch to an email provider that doesn’t access this data, like Proton Mail or Tutanota.

For those with more moderate privacy concerns, using PGP encryption alongside Gmail can be an adequate solution, especially since it's easier to implement than more secure alternatives.

Implementing PGP encryption with Gmail doesn't require setting up a new email account, making it a more accessible option for those who want to upgrade their security.

The learning curve for using PGP encryption with Gmail is also relatively flat, making it a more feasible option for those who are new to encryption.
