Explanation of the Types of Digital Certificates:

1. SSL/TLS Certificates:
   These certificates are used to secure websites by enabling HTTPS. They ensure that the data transmitted between a user’s browser and the web server is encrypted, preventing eavesdropping and data tampering.

2. Code Signing Certificates:
   These certificates are used by software developers to sign code and software applications. This assures users that the code is legitimate and has not been altered since it was signed.

3. Client Authentication Certificates:
   These are used to authenticate the identity of a user or a device before granting access to a server or system. They are commonly used in enterprise environments to enhance security.

4. Email Security Certificates (S/MIME):
   These certificates secure email communications by enabling encryption and digital signing of emails, ensuring the confidentiality and integrity of email messages.

5. Document Signing Certificates:
   These certificates allow users to sign digital documents with a digital signature. This ensures the document’s authenticity and integrity, commonly used in legal and business transactions.

6. Device Certificates:
   These certificates are used to authenticate devices within a network, such as IoT devices, ensuring that only trusted devices can connect to the network.
