“Secure / Multipurpose Internet Mail Extensions”
S / MIME is a certificate-based Encryption is the process by which data is made illegible and unusable for unauthorized viewers. In order to use or read encrypted data, you must decrypted will. A secret key is required for this. There are two types of top-level encryption: symmetrical and asymmetrical . In the symmetric encryption the same key is used to encrypt and decrypt the data.... solution that allows you to both encrypt and digitally sign a message. Message encryption helps you ensure that only the intended recipient can open and read the message. A digital signature helps the recipient to verify the This is something that needs to be identified and authenticated. An identity is typically a user who has login information in the form of a username and password. However, they can also be applications and services. of the sender.
Both digital signatures and message encryption are made possible through the use of unique digital certificates that contain the keys for verifying digital signatures and encrypting or decrypting messages.
To use S / MIME, you must have public keys for each recipient. Recipients must manage their own private keys, which must be permanently secured. If a recipient’s private key is compromised, the recipient must obtain a new private key and distribute new public keys to all potential senders.
