SSL certificate is a security method that protects data sent online. It is commonly used in email to transport layer security data of the mail server and client connection. This ensures that only authorized individuals can access sensitive information.
Definition of SSL
SSL certificate (Secure Sockets Layer) is a way to keep information safe when it's sent over the internet. SSL encryption makes a safe connection between a website and a browser so that no one can see the information that's being sent. A public key encrypts information from the email account, and the recipient's private key decrypts it.
Where to use SSL
Email encryption certificates are used for secure communication between the outgoing mail server and the client mail server. This way, unauthorized access is prevented, and confidential information is kept safe. SSL certificates use asymmetric encryption. The same is used in SSL/TLS protocol and cryptocurrencies for secure communication and transactions.
Types of SSL in emails
There are two main types of SSL certificates in emails: SSL/TLS and STARTTLS.
- SSL/TLS
It is a security protocol that encrypts data between a web server and a web browser. It is also used in email to encrypt the connection between the email server and the email client. SSL/TLS is the more secure option and is commonly used by businesses and organizations that need high levels of security.
- STARTTLS
STARTTLS encrypts email messages in transit between servers, providing effective security for email communication, though less secure than SSL/TLS.
How SSL certificate works in emails
SSL certificate secures the connection between the email server and the client. The server sends a certificate to verify its credibility. The client creates an encryption key and sends it to the server to encrypt all sent data between them. This is how SSL certificates protect data from unauthorized access.
Wrapping up
SSL certificate is a security protocol that encrypts data sent over the internet. It is used in email to secure the connection between the email server and the client. There are two types of SSL certificates in emails: SSL/TLS and STARTTLS. SSL/TLS is the more secure protocol and is commonly used by businesses and organizations that need high security. By using an SSL certificate in emails, businesses and individuals can ensure their email account’s communication is protected from unauthorized access.
