SSL Certificates – The Theory Behind 2-Way Certs
In common usage scenario, not everyone would have heard about 2-way SSL certificate because it is not a widely used method of secure certified encryption. In order to clearly understand the structural theory behind this alternative type of encryption, every user should be fully aware of the one way authentication first. Learning from the basics will better build your knowledge database and allow you to make informed decisions on what type of cert to buy. There are various types available including the premium extended validation and the multi-domain security certs from various leading providers. All of them are usually one-way authentication ssl certificates.
How one-way authentication works with ssl certificates?
The theory behind one-way SSL certificates is very simple. In order to identify your company’s server as the original, you have to install the certificates in it. The client computer or server will first establish a link with yours. This is commonly known as the handshake when the client introduces itself to the server. The SSL Certificate will be produced at this point and it will be verified against the private key stored with the CA name in the browsers. Once verified, the transaction is set to be completed without any issues.
Client Computer (Handshake) ———> SSL Server —-> Send certificate —->
CA cert key verified at Client computer –> Process Complete
Debriefing two-way authentication
The name is self descriptive because as it suggests, in this authentication method, two types of ssl certificates are exchanged between the server and client. The motive in simple terms is like double verifying the identity before a link is established and file transferred. Apart from the usual certificate verification sent by the server, in this process, the client will also send a cert to the server which will be verified with this database. The buyer should have vast knowledge to compare SSL and buy required keys as this is a much more complex process.
CA Cert A <—> CA Cert B (2-way verification)
Most of the ssl certificates used in here are signed and authorized by the certificate authority. Even though, self-signed certs can be used, better technical knowledge is a must and the process is prolonged. You have to install the cert and the private key on both SSL client and SSL server.
