In Linux, gnutls is a common application. It is also used to compile ffmpeg recently. However, it should be because the built-in gnutls is too old. Therefore, a new compilation is required for compilation errors. The following describes how to compile and install CentOS. Note: lib64 must be added to/etc/ld. so. conf. And do not use yum remove gnutls-devel. Do no

Red Hat security audit found that the widely used security class library GnuTLS has a vulnerability and cannot correctly verify specific forged SSL certificates. Therefore, attackers can exploit this vulnerability to launch man-in-the-middle attacks, it identifies this type of forged certificate as a valid certificate. GnuTLS is a free software implementation of SSL, TLS, and DTLS protocols. The vulnerabili

PHP openssl encryption extension usage Summary (recommended), openssl Summary Introduction In the history of Internet development, security has always been a topic that developers pay great attention to. To ensure data transmission security, we need to ensure that data sources (non-counterfeit requests), data integrity (not modified), Data Privacy (ciphertext, cannot be directly read), etc. Although the SSL

Add a custom encryption algorithm and OpenSSL encryption algorithm to openssl. I. Introduction This document introduces how to add a custom encryption algorithm to OpenSSL by taking the custom algorithm EVP_ssf33 as an example. Step 2 1. Modify crypto/object/objects.txt and register the algorithm OID as follows: rsadsi 3 255 : SSF33 : ssf33 2. Go to
