Secure Email
What is Encrypted Email
When emails are encrypted, the contents of the emails are scrambled so that only the intended recipient can access them.
Here's how email encryption typically works:
- A message is encrypted, or transformed from plain text into unreadable ciphertext, either on the sender's machine, or by a central server while the message is in transit.
- The message remains in ciphertext while it's in transit in order to protect it from being read in case the message is intercepted.
- Once the message is received by the recipient, the message is transformed back into readable plain text in one of two ways:
- The recipient's machine uses a key to decrypt the message; or
- a central server decrypts the message on behalf of the recipient, after validating the recipient's identity.
