What are SMIME Certificates?
SMIME (Secure/Multipurpose Internet Mail Extensions) certificates are digital certificates used to sign and encrypt email communications. They ensure the
integrity and
confidentiality of emails, allowing recipients to verify the sender's identity and ensuring that the message has not been tampered with during transit.
Authenticating the sender’s identity, thereby reducing the risk of phishing attacks.
Encrypting the email content, protecting it from being intercepted and read by unauthorized parties.
Ensuring the
integrity of the message, so recipients know it hasn't been altered.
How Do SMIME Certificates Work?
SMIME certificates use
asymmetric cryptography involving a pair of keys: a
public key and a
private key. When an email is signed using the sender’s private key, the recipient can use the sender’s public key to verify the signature. For encryption, the sender uses the recipient’s public key to encrypt the email, which can only be decrypted by the recipient’s private key.
