Just like a passport, a digital certificate provides identifying information, is forgery resistant and can be verified because it was issued by an official, trusted agency. The certificate contains the name of the certificate holder, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures) and the digital signature of the certificate-issuing authority (CA) so that a recipient can verify that the certificate is real.

To provide evidence that a certificate is genuine and valid, it is digitally signed by a root certificate belonging to a trusted certificate authority. Operating systems and browsers maintain lists of trusted CA root certificates so they can easily verify certificates that the CAs have issued and signed. When PKI is deployed internally, digital certificates can be self-signed.

The data structure used to transport and validate keys is called a digital certificate. A certificate protects the key by guaranteeing the identity of the issuer, the identity of the owner, and the purposes for which the key can be used. A certificate cannot be forged because the issuing authority digitally signs it. The signature is applied to a hash of the certificate. This enables clients to validate the issuer's identity and find any alteration. The client decrypts the hash using the issuer's public key and then compares the result to a separate hash it performs on the certificate. If the results match, the certificate is valid.

SSL stands for Secure Socket Layer. It sounds complicated, but it really is easy to understand. SSL certificates confirm the identity of your website, and encrypt customer information sent to, or received from your website. This will help the thief snooping on any data exchange between sites or your system with your customers.
When you have an SSL certificate protects your website, customers can be assured that the information they enter into any page that is secured and can not be viewed by online fraudsters. SSL is easy to deploy and install to protect your server.
An SSL (Secure Sockets Layer) is a digital certificate that authenticates the identity of a Web site and encrypts information sent to the server using SSL technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.

Certificates serve as a "passport" electronic entity established online information when trading on the site. When an Internet user attempts to send confidential information to a Web server, the user's browser to access the digital certificate of the server and establish a secure connection.

A digital certificate authenticates the Web credentials of the sender and lets the recipient of an encrypted message know that the data is from a trusted source (or a sender who claims to be one).

A Digital Certificate is an electronic secure "password" that allows a person, Organization to exchange data securely over the internet using PKI. Digital Certificate is also called a public key certificate or identity certificate. Digital Certificates are a way by which customers and businesses will utilize the security applications of Public Key Infrastructure (PKI). PKI contains the technology to enables secure e-commerce and Internet-based communication.

The digital certificate enables entities to share their public key in a way that can be authenticated. Digital certificates are used in public key cryptography functions they are most commonly used for initializing secure SSL connections between web browsers and web servers.Logo Design Services
