End to End Encrypted Email

3 minutes, 33 seconds Read

End to end encrypted email is the best way to keep your emails safe. It works by ensuring that your email is only ever decrypted on your device and never in the hands of a third party, like servers or service providers.

This technology isn’t new, but it’s increasingly important to use when dealing with sensitive data. It also helps prevent opportunistic “man-in-the-middle” (MITM) attacks, which can cause messages to be read while they’re in transit.

What is end to end encryption?

End-to-end Encrypted email is a form of cryptography that ensures data is safe in transit. It prevents hackers, government agents and other entities from reading the content of your message.

E2EE works by scrambling your data into ciphertext, which is unreadable to anyone except the intended recipient. The recipient can then decrypt the ciphertext using a key that is only available to them.

Compared to other types of encryption, E2EE is more resistant to man-in-the-middle attacks and is less likely to be broken. This type of security is particularly useful for sensitive information, such as banking and credit card details.

End to end encrypted email is a security feature that is now built into many popular messaging apps, such as WhatsApp and Telegram. It’s also included in Proton Mail, which provides complete encryption of your messages and chats.

Encryption in transit

Encryption in transit is a common security precaution that ensures data is unreadable to unauthorized users. This helps prevent cybercriminals from stealing sensitive information that is in transit and causing hefty fines, legal fees and losses of user trust.

When data is encrypted, it scrambles text into ciphertext that no human or bot can read. This is the only way to protect your data from a data exfiltration or system compromise, and it also helps keep your company safe from major breaches that can lead to a loss of revenue, a drop in user confidence and a whole host of other negative consequences.

In addition to encryption in transit, PhoenixNAP also enables you to fortify your files during processing by using confidential computing, which isolates all data and workloads from the CPU enclaves where they are processed. Combining encryption in transit with this cloud computing security feature ensures end-to-end data security as files move from device to server and back again, protecting valuable files from a breach or theft.

Encryption at the device level

Encryption at the device level is a form of end to end encryption that protects data before it leaves the device and before it gets sent to its destination. This protects business and personal data, and prevents hackers from stealing or selling it.

Device-level encryption works on an individual computer’s hard drive or other storage device. It encrypts all data on a drive automatically, making it indecipherable to third parties. This is commonly implemented with full disk encryption, which protects all of a device’s user data partition when it is booted up.

Another type of device-level encryption is file-based encryption, which encrypts only specific files or folders. This method of encryption is usually used for personal data files, such as word documents and spreadsheets. It also allows IT administrators to select which files should be encrypted.

Decryption at the device level

End to end encrypted email means that data is encrypted at the device level before it leaves your computer or phone, and is not decrypted until it reaches its intended destination. This ensures that hackers and service providers can’t access your information.

To encrypt your emails, you generate two keys: a public key and a private key. The public key is shared between you and your recipient, while the private key is kept secret.

This method of encryption is called asymmetric cryptography, and is based on the idea that one key is used to encrypt messages while the other is used to decrypt them. Asymmetric cryptography is more secure than symmetric encryption because it requires each sender and receiver to do a one time preparation that involves the generation of personal random numbers, or keys.

End to end encryption is the best way to ensure your emails are encrypted, as long as you and your recipients use it. However, it doesn’t guarantee 100% protection against external or internal threats.
