Secure Sockets Layer (SSL) is a protocol for enabling data encryption and used to protect the communication between user (client browser) and the company (server). Encryption is a process of coding and decoding user's information. The number of bits (16-bit, 32-bit, 64-bit, 128-bit, 256-bit) tells you the size of the key. We are selling SSL certificates for domain, organization and extended validation. Our SSL certificates start from less than 1 US$ per month. Search engines now prefer https instead of http which is not secure.
