If you’re looking for a VPN protocol that can encapsulate PPP traffic using the Secure Sockets Layer (SSL), you may want to consider using the OpenVPN protocol. OpenVPN is a robust and highly configurable VPN protocol that can be used in a variety of scenarios, and it’s known for its ability to provide a high level of security.

Introduction
Which VPN Protocol Encapsulates PPP Traffic Using the Secure Sockets Layer (?) is a common question asked by those who are considering using a Virtual Private Network (VPN). The answer to this question is that there are many different protocols that can be used to encapsulate Point-to-Point Protocol (PPP) traffic, but the most common and most secure protocol is the Secure Sockets Layer (SSL).
VPN Protocols
The main VPN protocols are:
Secure Sockets Layer (SSL)
SSL was developed by Netscape in the mid-1990s as a means to secure communications between web browsers and web servers. Today, SSL is widely used in securing communications between all kinds of applications, including web browsers, email clients, virtual private network (VPN) clients and servers, instant messaging programs, and many more.
SSL uses a combination of public key and symmetric key cryptography to provide a high level of security. In SSL, the server’s public key is used to encrypt data that is then transmitted to the client. The client then uses the server’s public key to decrypt the data. The client also generates a random symmetric key that is used to encrypt data that is transmitted back to the server. The server then uses the client’s symmetric key to decrypt this data.
While SSL is very effective at providing security, it does have some drawbacks. One is that it can be computationally intensive, which can make it slow. Another is that it only provides point-to-point security, which means that if there are multiple parties involved in a communication, each party must have its own SSL connection to the other parties. Finally, SSL connections can be subject to attack by man-in-the-middle (MITM) attackers.
Transport Layer Security (TLS)
Transport Layer Security (TLS) is the most commonly used VPN protocol. TLS uses public key cryptography to authenticate both the server and client and to negotiate a shared encryption key. Once a connection is established, data can be transmitted securely over the internet using symmetric-key cryptography with message authentication codes (MACs) to ensure data integrity. TLS is available in two different versions: SSL 3.0 (which was exposed to the “POODLE” attack in 2014 and is no longer considered secure) and TLS 1.0, 1.1, or 1.2 (the latest version, which provides the best security). Many popular web browsers support TLS 1.0 but not SSL 3.0, so it’s important to make sure that your VPN uses TLS 1.0 or higher.
Internet Protocol Security (IPsec)
Internet Protocol Security (IPsec) is a secure communications suite that cryptographic protocols designed to provide security for Internet Protocol (IP) traffic. IPsec is often used in Virtual Private Networks (VPNs) to protect traffic traveling over public networks such as the Internet.
IPsec supports two modes of operation: transport mode and tunnel mode. In transport mode, only the payload of the IP packet is encrypted and/or authenticated. The header of the IP packet is not encrypted or authenticated. In tunnel mode, the entire IP packet is encrypted and/or authenticated.
IPsec uses a variety of encryption and authentication algorithms to secure traffic. Encryption algorithms used with IPsec include DES, 3DES, AES, and Blowfish. Authentication algorithms used with IPsec include MD5, SHA-1, and RIPEMD-160.
IPsec can be implemented in a number of ways. It can be implemented at the network layer using an IP Security Gateway (IPSecGW) or it can be implemented at the application layer using a Virtual Private Network (VPN) client software program.
Secure Shell (SSH)
Secure Shell (SSH) is a protocol used to encapsulate PPP traffic using the secure sockets layer (SSL). The advantage of using SSH over other protocols is that it provides a higher level of security by encrypting all data that is transmitted over the connection. In addition, SSH uses a two-way authentication process that verifies both the identity of the user and the server before any data is exchanged.
Conclusion
Thus, we have seen that there are several VPN protocols that can be used to encapsulate PPP traffic using the secure sockets layer. Each of these protocols has its own advantages and disadvantages, and so it is important to choose the right protocol for your specific needs. In general, however, SSL-based VPNs tend to be more secure and efficient than their counterparts.
