Cryptography is the science of creating and decoding coded writing to ensure content security. Cryptographic service providers offer hardware or software-based encryption and decryption for data security. They can use symmetric or asymmetric encryption, with public key cryptography using two different keys. Smart cards are used to store sensitive data and cryptographic smart cards include cryptographic hardware. The Microsoft Cryptographic Service Provider is a software module that performs cryptographic authentication, encryption, and decryption in a Windows environment.
Cryptography is the science of creating and deciphering coded writing in order to ensure the security of content. Encryption has been used for thousands of years to keep messages secret, and with the Internet, new needs and challenges have emerged to protect information such as email, credit card transactions and business data. A cryptographic service provider provides this type of protection.
A cryptographic service provider, also known as a cryptographic service provider or CSP, is a means of providing hardware- or software-based encryption and decryption. Encryption refers to translating data into an encrypted file that requires reading a secret key or password. It is a widely used and effective means of ensuring data security. Decryption refers to decoding data that has been encrypted so that it can be read as a normal communication, or plain text, in the source language.
Cryptographic service providers can use symmetric or asymmetric encryption. Asymmetric cryptography is also known as public key cryptography. In symmetric encryption, the same key encrypts and decrypts the message, making the operations symmetric. Asymmetric or public key cryptography uses two different keys. The public key is a key that everyone knows and is used by a group, anyone can send a message to any other member of the group. The private key is used by the individual member to decrypt the message. Asymmetric encryption is also called Diffie-Hellman encryption after its inventors, Whitfield Diffie and Martin Hellman, who came up with the system in 1976.
For example, in a Windows environment, the Microsoft Cryptographic Service Provider is a software module that can function independently and perform cryptographic authentication, encryption, and encryption. Although it may seem like a synonym, coding and encryption are not synonymous: encryption is the conversion of data into a stream of bits. The components include, at a minimum, a dynamic link library (DLL) and system program interfaces (CryptoSPI). CSPs can contain their own implementation of the function or their functions can be implemented in a Windows based service program, which would be a program managed through the Windows service control manager. Hardware implementations include a secure coprocessor or smart card.
A smart card is a credit card-sized plastic card with electronic memory and sometimes having an integrated circuit, in which case it is also called an integrated circuit card (ICC). They are used to store sensitive data, including medical records, digital cash, and to generate network IDs. Information is added to or extracted from a smart card using a smart card reader. Cryptographic smart cards include cryptographic hardware and are used, for example, for digital signatures. The Windows Cryptographic Service Provider can access data on cryptographic smart cards.
