Data Encryption Standard
DES is a symmetric key block cipher algorithm developed by IBM. It has been adopted as an the standard in the US. Data Encryption Standard enciphered whole messages by means of public-key systemswith a conventional cryptosystem.
Decryption
The process of converting encrypted code back into its original form, so it can be processed. Often, a decryption key is required. The key uses an algorithm to reverse the encryption algorithm. The more complex encryption algorithms make it nearly impossible to eavesdrop without access to the key.
DigiCert
In 2003 a new SSL provider, DigiCert, Inc. established itself as a major SSL Certification Authority, offering Cheap SSL Certificates at a fraction of the cost charged by other SSL Authorities, like Thawte, and Verisign.
Digital Certificates
Digital authentication systems have become an essential part of e-business on the Web. Using very sophisticated encryption techniques, digital signatures allow ecommerce organizations to electronically certify their identity, online payment, or authenticity of any electronic document. Like a passport, Digital Certificates offer access, through the use of a private key and a public key. The two keys work together to verify and authenticate data with an encrypted "fingerprint" that can be used to verify the contents of the certificate, or "cert". Digital certificates are issued by trusted Certificate Authorities. For instance, the public key of the ecommerce merchant's digital certificate is used to encrypt the shopper's order before it is delivered to him.
