producing digital signatures, developed by NIST and the NSA. To sign a message. For example, say Jean uses the DSA Sign Algorithm to encode a digest of the message using her private key. For all practical purposes, there is no way to decrypt this information. However, anyone who receives the message and accompanying digital signature can verify the signature by using the DSA Verify Algorithm to process the following information: the received signature; a digest of the received message; and Jean’s public key.

Extended Validation:

Expanded validation authentication certificate is likewise named a green bar certificate. It offers powerful encryption to the site as well as takes after the solid verification process. Extended validation certificate is better than domain and business approval thus, are somewhat costly. Also, broadened approval offers phishing insurance therefore, numerous sites have proceeded onward EV SSL declaration. Clients effortlessly put trust on sites that have EV SSL authentication as it outfits most noteworthy legitimacy and dependability.

SNI remains for server name sign that is an expansion to TLS protocol. SNI enables a customer to show multiple certificates on a similar IP address and TCP port number. The vast majority of the web programs bolster SNI augmentation.

SSL handshake

The SSL handshake is the term given to the process of the browser and web server setting up a SSL session. The SSL handshake involves the browser receiving the SSL certificate and then sending "challenge" data to the web server in order to cryptographically prove whether the web server holds the SSL key associated with the SSL certificate. If the cryptographic challenge is successful then the SSL handshake has completed and the web server will hold a SSL session with the web browser. During a SSL session the data transmitted between the web server and web browser will be encrypted. The SSL handshake takes only a fraction of a second to complete.

SSL (Secure Sockets Layer)

SSL is secure socket layer.It enables secure, encrypted communication over the Internet. SSL is also supported by all popular web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Internet Explorer, Apple Safari, mobile browsers on iOS and Android, and many more.

SSL Accelerator

SSL Accelerator is used to improve network speed. It is a hardware devices.

SSL Proxy

SSL Proxy allows non-SSL aware applications to be secured by SSL. The SSL Proxy will add SSL support by being plugged into the connection between the browser (or client) and the web server.

SSL Port / HTTPS Port

A port is the "logical connection place" where a browser will connect to a web server. The SSL port or the HTTPS port is the port that you would assign on your web server for SSL traffic. The industry standard is port 443 - most networks and firewalls expect port 443 to be used for SSL.

TLS (Transport Layer Security)

TLS is short for Transport Layer Security. The TLS protocol was designed to succeed the SSL protocol. Think of TLS as the "sequel" to SSL. Both use the same certificates and most servers can support both protocols.

Types of SSL certificates:

Many individuals are confused about various sorts of SSL and their use. However, there are principally three types of certificates, domain validation, business validation, extended validation. There are numerous other SSL endorsements which are classified by their use, Wildcard SSL for subdomains security, Multi-Domain SSL to secure different sites, code signing authentication used to ensure programming.

Moreover, X.509 Certificate is an international standard used to validate Digital Signature

128 bit SSL

128 bit SSL is also referred to as strong SSL security. The 128 bit tells users that the size of the encryption key used to encrypt the data being passed between a web browser and web server is 128 bits in size (mathematically this would be 2 to the power of 128). Because the size of the 128 bit key is large it is computationally unfeasible to crack and hence is known as strong SSL security.

Most web servers and web browsers support 128 bit SSL. However some versions outside of the US will only support 40 bit SSL and should be upgraded.
