Indian tech company eMudhra announces withdrawal from certificate business after security incident

Indian tech company eMudhra is withdrawing from the certificate business following a security incident. The issue was made public by a cybersecurity researcher who discovered that one of the company's private keys was a simple number, rather than a random 384-bit number as expected. Specifically, the private key was found to be just the number four, which is a significant security vulnerability. This discovery led to the company's decision to exit the certificate business. The security incident was first revealed by the researcher in a blog post. The vulnerability was apparently severe enough to prompt eMudhra's withdrawal from the certificate business.
