A certificate in pfx format needs to be converted to the CER format at work. The original practice is to first import the pfx format certificate to the browser, and then export it from the browser, however, this is too slow for batch operations. You

Use openssl to build a Root CA in CentOS 6 I. Introduction OpenSSL is an open-source encryption tool. In a Linux environment, we can use it to build a CA for certificate issuance. It can be used in an enterprise's internal encryption tool, the

Many may have the same deep experience as myself. Using the OpenSSL library to write an encrypted communication process, the code can be easily written, but the entire work has taken several days. In addition to compiling the program successfully

Different certificates are stored in different formats (such as whether the public key or private key is encrypted for storage, a single certificate, or multiple certificates), and are encoded differently (der/base64) different standards (such as
