About OpenSSL OpenSSL
SSL is an abbreviation for the Secure Socket Layer protocol, which provides covert transmission over the Internet. Netscape Company introduced the SSL protocol standard at the same time as the first web browser, there are now 3.
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
OpenSSL introduction and compilation steps on Windows, Linux, and Mac systems
OpenSSL Introduction: OpenSSL is a powerful Secure Socket Layer password library, which includes major cryptographic algorithms, common keys, certificate encapsulation
Rsautl is a tool for RSA, a subset of the features of RSA and dgst that can be used to generate digital signatures, verify digital signatures, encrypt and decrypt files .Pkeyutl is a generic tool for asymmetric encryption, which is roughly the same
1. Overview of Asymmetric encryption algorithmsAsymmetric encryption algorithm is also called Public key algorithm, which solves the problem of symmetric encryption algorithm key distribution, the basic features of asymmetric encryption algorithm
In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process. This chapter describes how to use the OpenSSL library to
1. Summary of information and digital signatureInformation Summary: Processing the data to obtain a fixed length of the results, its characteristics input:1, the output length is fixed. That is, the output length is independent of the input length.2,

However, I follow the steps above, the HTTPS service does not start, always prompts the certificate file does not exist or the format is illegal. It's been a long time,
Post an informed answer:
There is also a service that tests whether the Web site is affected: Test your server for Heartbleed (cve-2014-0160) (now long 503)
