how to use openssl

Certificate file generation 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. Except for compiling

Step 1. Generate the RSA private key file : \> OpenSSL genrsa-out bexio. pem 1024 : To encrypt the generated RSA private key file (des3 encryption) :\> OpenSSL genrsa-des3-out bexio. pem 1024   Step 2. Generate a Certificate Signing Request

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 following is a powerful OpenSSL tool. in Linux,

Before accessing the Google IMAP server, we need the OpenSSL tool. telnet is not powerful when it encounters a connection that requires SSL.  OpenSSL: Http://www.openssl.org/source/ For how to compile the OpenSSL library, see my other blog. 

Method 1: Generate Private Key OpenSSL genrsa-out server. Key 1024 Generate a self-Signed CER Certificate Format file with the private keyOpenSSL req-New-X509-days 3650-key server. key-out server. CRT-subj "/C = Cn/ST = mykey/L = mykey/o =

Recently received a task to convert a CER format security certificate to PEM format, originating from the LoadRunner script does not support CER format security certificates. Because of the security certificate format a lot, pay attention to many,

Recently in the development of the public number found a problem, that is PHP7.1 in the mcrypt has been discarded, then only to find a way to solve this problem, today to everyone about how I solve this problem and solve the idea. The new features

Zhou Leilei Currently, the SSL protocol is widely used. How can I quickly find out the root cause of the problem when the SSL server's Identity Authentication fails? This document, combined with the command line tool s_client provided by openssl,

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

Background Due to the heart of openssl recently, I changed the ssl library 1.0.1g. I need to use this library to connect to the server. However, after I find that the Library is replaced, for some domain names, the ssl handshake will fail. In order

OpenSSL has powerful functions, such as seamless Io filtering, secure sockets, and data encryption and decryption, in fact, the certificate authentication function of OpenSSL can implement the version control function of the C/S Mode Program. The

This document draws on the files on the Internet and makes some modifications on its own. It mainly solves some problems caused by inconsistencies and not details during the test. OpenSSL Installation Centos Yum install OpenSSL-devel # Include #

OpenSSL the configuration of the environment, I will not say, you can refer to the previous blog. Before we compute the MD5 value of the string, in this article, we'll discuss a file's MD5 value, cut the crap, just give us the code, the dry stuff: #

The Afaria documentation mentions that you can generate a certificate request either with Mac computer keychain or Windows IIS.However, IIS generates a certificate request that Apple does not recognize, prompting invalid CertificateIt's too much

Preface openSSL is a powerful encryption tool. many of us are already using openSSL to create RSA private key or certificate signature requests. However, you can use openSSL to test the computer. speed? You can also use it to encrypt files or
