SSL Certificates - Secure SSL Certificates and Cheap SSL Certs

A security protocol,cryptographic protocol or encryption protocol is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods.
A protocol describes how the algorithms should be used. A sufficiently detailed protocol includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program.
Secure Cryptographic protocols are generally used for the secure transport of application level data. cryptographic protocols invariably incorporate features of:

E.G.. TLS - Transport Layer Security - is a cryptographic protocol used to secure http web connections. Using authentication mechanisms with X.509 systems - a secure key setup phase where encryption keys are created by using public-key cryptography – together with application level function. Bearing in mind that Standard TLS is exempt from non repudiation reference.
Other varieties of cryptographic protocol can be understood in different ways: Cryptographic application protocols can implement alternative key agreement methods. These can be referred to as Cryptographic Protocols. As an example, Transport Layer Security uses Diffie-Hellman key exchange technology. Diffie-Hellman can be considered as a complete cryptographic protocol on its own.
Blind signature techniques can be emplyed for digital-cash and digital-credential situations to ensure the user has validity without refeasing identity within the transaction. Secure digital time-stamping will prove that clocked data was revealed. Secure shared data can be revealed in confidential circumstances with each party able to see or record their own data and not the data of all parties.
