How does the OVH SSL Certificate work?
What it does
The SSL technology (Secure Sockets Layer) is used to secure the transmission of data over the internet. It encrypts and protects the data transmitted with the help of the HTTPS protocol. The SSL assures your site visitors that their data will not be intercepted by fraudsters.
SSL security rests on two principles:
All data transmitted is rendered unintelligible, except between the visitor making the connection and the server that hosts the website.
Encryption is the basis of data integrity and confidentiality.
The Domain Validated (DV) certificate offered by OVH does not guarantee that a site has been identified by any certification authority. Nonetheless, it provides authentication of the exchanges made between a user and the OVH servers, which is necessary to securing data transfers.
Authentication of a certificate generates a pair of digital keys:
The principle step by step:
The private key:
It is installed on the server and creates your site's certification stamp.
The public key:
The DV certificate is the other side to the SSL certificate, which is also installed on your site. It allows your visitors to encrypt their data, which is essential when sending sensitive personal information (bank details, national insurance number etc.). Data is encrypted prior to being sent, and only the private key can uncrypt it.
- Request secure connection via SSL
Verifications made on the certificate at this stage:
- Signature of a trusted third party
Transmission of unique encryption key
(encoded with server's public key)
Encryption key uncrypted by server, using its private key
- A secure connection is established
