SSL certificates include: The domain name that the certificate was issued for Which person, organization, or device it was issued to Which certificate authority issued it The certificate authority’s digital signature Associated subdomains Issue date of the certificate Expiration date of the certificate The public key (the private key is kept secret)
In order to provide a high degree of privacy, SSL encrypts data that is transmitted across the web. This means that anyone who tries to intercept this data will only see a garbled mix of characters that is nearly impossible to decrypt. SSL initiates an authentication process called a handshake between two communicating devices to ensure that both devices are … Read more
SSL is the direct predecessor of another protocol called TLS (Transport Layer Security). In 1999 the Internet Engineering Task Force (IETF) proposed an update to SSL. Since this update was being developed by the IETF and Netscape was no longer involved, the name was changed to TLS. The differences between the final version of SSL … Read more
There are several different types of SSL certificates. One certificate can apply to a single website or several websites, depending on the type: Single-domain: A single-domain SSL certificate applies to only one domain (a “domain” is the name of a website, like www.cloudflare.com). Wildcard: Like a single-domain certificate, a wildcard SSL certificate applies to only one domain. However, … Read more
Originally, data on the Web was transmitted in plaintext that anyone could read if they intercepted the message. For example, if a consumer visited a shopping website, placed an order, and entered their credit card number on the website, that credit card number would travel across the Internet unconcealed. SSL was created to correct this … Read more
Technically, anyone can create their own SSL certificate by generating a public-private key pairing and including all the information mentioned above. Such certificates are called self-signed certificates because the digital signature used, instead of being from a CA, would be the website’s own private key. But with self-signed certificates, there’s no outside authority to verify … Read more
SSL, or Secure Sockets Layer, is an encryption-based Internet security protocol. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications. SSL is the predecessor to the modern TLS encryption used today. A website that implements SSL/TLS has “HTTPS” in its URL instead of “HTTP.”
Enumerating as much of the application’s content as possible is only one element of the mapping process. Equally important is the task of analyzing the application’s functionality, behavior, and technologies employed, in order to identify the key attack surfaces that it exposes, and begin formulating an approach to probing the application for exploitable vulnerabilities. Some … Read more
