If you’re looking for a VPN protocol that can encapsulate PPP traffic using the Secure Sockets Layer (SSL), then you might want to consider using the OpenVPN protocol. OpenVPN is a robust and highly configurable VPN protocol that can be used in a variety of settings, including on public Wi-Fi networks.

VPN protocols encapsulate PPP traffic using the Secure Sockets Layer (SSL) or the Transport Layer Security (TLS) protocols. SSL and TLS are both cryptographic protocols that provide communication security over the Internet. SSL is the predecessor of TLS, and TLS is the successor of SSL.
Secure Sockets Layer (SSL)
SSL is a security protocol that provides encrypted communication between a client and a server. SSL is often used to protect sensitive information such as credit card numbers and passwords. When a VPN uses SSL to encapsulate PPTP traffic, it is said to be using SSL VPN.
Secure Sockets Layer (SSL) is a protocol that encapsulates Point-to-Point Protocol (PPP) traffic using the Secure Sockets Layer () framework. SSL provides a secure link between two devices, ensuring that all data passed between them is encrypted and therefore protected from eavesdropping.
SSL Record Protocol
Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser, or a mail server and a mail client (e.g., Outlook).
SSL allows sensitive information such as credit card numbers, social security numbers, and login credentials to be transmitted securely. Normally, data sent between browsers and web servers is sent in plain text—leaving users vulnerable to eavesdropping. If an attacker is able to intercept all data being sent between a browser and a web server, they can see and use that information.
SSL is layered on top of the Internet’s TCP/IP protocol to provide end-to-end encryption of data in transit. SSL uses public-key cryptography for encrypting data during transmission. Once the connection is made using SSL, the session key that is used for the encryption/decryption of data during the session is negotiated. This process uses the SSL Record Protocol.
SSL Change Cipher Spec Protocol
The SSL Change Cipher Spec Protocol is used to change the encryption key for a secure connection. This protocol is used in conjunction with the SSL Handshake Protocol. The Change Cipher Spec Protocol is used to notify the server that the client will begin using the new encryption key.
SSL Handshake Protocol
The SSL handshake is an authentication process that is used to negotiate an encrypted connection between a web server and a web browser. This process uses cryptography to ensure that communications between the two parties are private and tamper-proof.
The handshake begins when the browser sends a request to the server to establish a connection. The server then responds with its public key and a signed certificate. The browser verifies the certificate and if it is valid, it uses the public key to encrypt a random number. This number is then sent back to the server, which decrypts it using its private key.
If the decrypted number matches the one that was sent by the browser, then the connection is considered secure and communications can proceed. Any data that is exchanged between the two parties will be encrypted using this process.
Transport Layer Security (TLS)
While SSL is the most popular encryption protocol on the Internet, there are a number of other protocols that can be used to encrypt traffic. One of these is Transport Layer Security (TLS), which is a successor to SSL. TLS is a more recent protocol, and it offers a number of advantages over SSL.
Transport Layer Security (TLS) is a cryptographic protocol designed to provide privacy and data security between two or more communicating computer systems. TLS uses a combination of cryptographic techniques, including symmetric-key cryptography, public-key cryptography, and hashing, to ensure the confidentiality and integrity of data transmitted over a network. TLS is an updated and more secure version of theSSL protocol.
TLS Record Protocol
The TLS Record Protocol is responsible for fragmentation, compression, and adding an integrity check using a MAC to the data. It uses different methods for these purposes with different levels of security. The data is divided into small fragments before it is processed by the Record Protocol. Each fragment is encapsulated and processed separately. TLS supports two different types of data encapsulation. One uses streaming mode and the other uses block mode.
In streaming mode, each fragment is compressed and then encapsulated. The encapsulation includes a message digest which is used to verify the message integrity when it arrives at its destination. This message digest is created using a MAC. Streaming mode is used when bulk data transfer is required, such as when sending files.
Block mode can be used for both compression and encryption of data. In block mode, the data is first padded so that it falls on an even byte boundary, then it is compressed, and finally it is encrypted. A message digest is not used in block mode, so this method provides less security than streaming mode.
TLS Change Cipher Spec Protocol
The TLS Change Cipher Spec Protocol is used to change the encryption algorithm in use by a TLS connection. This allows for more flexibility in the algorithms used and supports the use of new algorithms as they are developed.

TLS Handshake Protocol
The TLS handshake protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When a TLS-enabled server receives a connection request from a TLS-enabled client, it responds with a server hello message containing a server certificate, the supported cipher suites, and other parameters. The client verifies the server’s certificate and responding with a client hello message of its own, including the selected cipher suite from the list provided by the server and other parameters. The server then sends its own client hello message, and the two sides exchange key information. At this point, both sides have enough information to generate shared secret keys, which are used to encrypt subsequent communications in both directions.
In conclusion, the best VPN protocol for encapsulating PPP traffic using the secure sockets layer is PPTP. PPTP uses a strong encryption algorithm that is effective in securing data transmissions. It is also compatible with a wide range of devices and operating systems.
