The DigiCert SSL certificate reviews listed below will help you determine whether DigiCert is a good company to buy SSL certificates from. The reviews have been verified to be from real DigiCert customers. If you want to compare DigiCert SSL certificates with certificates from other SSL providers, use our SSL Wizard. If you have ever purchased or received a certificate from DigiCert, please. I’ve just discovered that one of our servers is not serving up it’s SSL certificate chain correctly. This is fine for modern web browsers who trust the COMODO certificate, but for older browsers/operating systems you need to support higher up the trust chain. If you're accessing a site that uses a certificate from a well-known certificate authority like Verisign / Thawte / GoDaddy / DigiCert / etc..., then it should be as simple as downloading the latest CA bundle and telling cURL to use it. Sometimes, even the most effective webmaster has problems with SSL/TLS Certificates. Ordering the right certificate, creating a CSR, downloading it, installing it and testing it to make sure there are no problems are all areas where a webmaster can encounter problems. Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP) for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS), or, formerly, its predecessor, Secure Sockets Layer (SSL). The protocol is therefore also often referred to as HTTP over. SSL was developed by Netscape in 1994, and with input from the Internet community, has evolved to become a standard. It is now under the control of the international standards organization, the Internet Engineering Task Force (IETF). One-Way and Two-Way SSL. SSL can be configured one-way or two-way: With one-way SSL, the server must present a certificate to the client, but the client is not required to present a certificate to the server. Some interesting notes: Newer updates to web browsers are turning off SSL v3 in favor of TLS (Transport Layer Security, essentially SSL v4); attackers could cause problems with TLS so that the browser dropped back to SSL v3, which can be hacked. Tutorial: Configure Apache Web Server on Amazon Linux 2 to Use SSL/TLS Secure Sockets Layer/Transport Layer Security (SSL/TLS) creates an encrypted channel between a web server and web client that protects data in transit from being eavesdropped on.
