openssl pkcs7 encrypt

OpenSSL is an open source SSL implementation. The simplest and most important application based on the OpenSSL directive is to use Req, CAs, and X509 to issue a certificate.OpenSSL provides command-line options and interactive two ways to perform

Simple use of OpenSSL to generate secret keys To add SSL to servers such as Postfix and Apache, enhance the security factor, You need to use certificate (certificate). This certificate can be obtained from the official ca. Or you can generate one

OpenSSL encoding rules1. data encoding format Openssl data encoding rules are based on ans.1. What is ans.1? An Explanation on top of the project ASN.1 (Abstract Syntax Notation One) is a structured Description Language, which consists of two parts:

OpenSSL source code mainly consists of the eay library, SSL library, tool source code, sample source code, and test source code.The eay library is a basic library function and provides many functions. The source code is stored in the crypto

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

Various types of certificates because the contents of the store are different (such as whether the public/private key is encrypted storage/single certificate or multi-certificate, etc.), the adoption of different encoding (DER/BASE64), the standard

Article title: Introduction to OpenSSl. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In linux, we often see

The concepts related to certificates are really tricky because they haven't been exposed to certificate encryption before, because there's a whole new term coming up that looks like something else in another field, not something that we're familiar

Certificate creation depends on the encryption algorithm, see http://yunweigou.blog.51cto.com/6299641/1637108 Preface, with the development of the network, because the use of HTTP protocol communication between the two sides of the data is clear-
