Certificates for Authentication

We provide solutions for creating an environment for authenticated electronic communications and transactions. We help to manage digital certificates for private transactions.

For a secured transaction, we make use of Public and Private Keys along with the information to be sent. These Public and Private Keys are used at the time of encryption and decryption processes. The certificate's corresponding Public key helps to verify the identity of the sender. The cryptographic keys in a certificate have hundreds of characters. The random nature and the length make cryptographic keys more complicate to guess.

A digital Certificate contains

• Distinguished Name (DN)
• Associated public key
• The certificate is digitally signed by a third party called the Certificate Authority (CA)

Digital certificates are mainly provided for privacy and data integrity uses. The certificates and the associated Key detect the changes in data

Various steps in Certificates for Authentication

• The data packet from the client is sent to the server. The data packet includes the user certificate that contains public key, the random data and the private key
• Server checks user’s certificate with the help of the CA certificate
• Server verifies the private key by checking the signature
• Server compares the user certificate with the rules in the server configuration file and finalizes whether login is allowed or not
