How Email Encryption Works
Posted: Sun Dec 15, 2024 5:24 am
As we covered earlier, email encryption works by using a cryptographic algorithm and a key to scramble the content of an email, making it unreadable to anyone except the intended recipient, who has the decryption key.
If you rely solely on your email password as a standard protection method, it will only prevent access to your mailbox, but it will not prevent someone from intercepting your important messages in transit or on the recipient's side. Encryption is the only reliable way to protect your information.
Here’s a simple explanation of how email encryption generally works:
Key Generation: Generates cryptographic keys (public uk people whatsapp number and private keys) for encryption and decryption.
Encryption: The sender uses the recipient's public key to encrypt the message and attachments.
Transmission: Encrypted emails are sent over the Internet and cannot be intercepted.
Decryption: The recipient uses their private key to decrypt this email back to plain text.
Digital Signatures: Senders can choose to digitally sign emails using their private key to ensure their authenticity and integrity.
How to encrypt email and send it securely?
The process of encrypting your emails may seem complicated, but most of the most common email clients and services already have encryption capabilities built in for their users. Even if it isn't built in, you can easily encrypt your emails yourself in just a few minutes if you follow the instructions.
Here are simple quick instructions on how to encrypt your emails in the most popular email clients:
How to Encrypt Emails in Gmail
Gmail supports email encryption via S/MIME, which is integrated into your Google Workspace account. Please follow the steps below to encrypt your email:
Follow the instructions from Google for your Google Workspace administrator account to activate Managed S/MIME.
Compose your email as you normally would.
Click the lock icon next to the recipient's email address to set the encryption level.
Modify the S/MIME settings by clicking View Details or select an encryption level to adjust the settings.
Note: Green indicates S/MIME encryption, which requires a private key to decrypt.
Grey means the email is protected by TLS. This only works if both parties have TLS.
