Digital certificate

A digital certificate is an electronic document which conforms to the International Telecommunications Union’s X.509 specification. X.509 is about message integrity, authentication and authorization.

The most common use of a digital certificate is to verify that a user sending a message is who he or she claims to be, and to provide the receiver with the means to encode a reply.

A digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA). It contains your name, 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 so that a recipient can verify that the certificate is real.

The use of certificate Management in Matrix Products:

Upcoming Matrix Product NAVAN CNX200 (supporting voice & data) gives the facility of certificate management.

Self Signed & CA signed certificate are both supported in Matrix product:

Self–signed certificate:

• A self signed certificate is created by user

• The self signed certificate is faster to create but not signed a trusted CA organization

• The self signed certificate requires that any client that connects over an SSL connection to the server that installs these certificates be configured to trust the signer of this certificate.

• As the certificate has been self signed, the signature is not likely to be in the client trust file & must be added

CA signed certificate:

• A CA certificate is a certificate created by a trusted CA organization that issues these certificates

• The CA organization creates the certificates which contain a public key & the identity of the owner and it is up to the CA organization to verify applicant’ credentials

• The certificate is then delivered to an endpoint which is pre-configured to trust certificates that created/assigned at a CA organization

Now what is Certificate Authority?

CA is a commonly trusted third party that is relied upon to verify the matching of public keys to identity, e-mail name, or other such information.

The benefits of certificates and CAs occur when two entities both trust the same CA. This allows them to learn each other's public key by exchanging certificates signed by that CA
