Security properties of certificates
- [Instructor] We've discussed the purposes of certificates, including those used to encrypt conversations. To encrypt traffic as it comes and goes, there needs to be an algorithm in place that is secure to keep sensitive information from being exposed to the outside world. Certificates that verify identity also needs security. It would be a less desirable scenario if someone were able to forge our digital signature and start issuing bogus certificates in our name. One important element of a certificate then is the secure hashing algorithm. In this sample certificate, we can see that there is a secure hash algorithm of SHA1. SHA1 stands for Secure Hashing Algorithm. And it refers to the method used by the computer to generate a unique pattern for scrambling each piece of data. For several years, SHA1 was the hashing algorithm that we were using. But a few years ago, articles started circulating about research indicating the weaknesses and vulnerabilities in SHA1. And that gave birth…
