1. First generate the server-side private key Server.key, the same can also generate the client's Key,client.key: OpenSSL genrsa-des3-out Server.key 1024 2. Generate the signature's public key CLIENT.CRT: OpenSSL req-new-x509-key client.key-out client.crt-days 3650 3. Generate CLIENT.CRT and SERVER.CRT for Server.key and Client.key signatures using CLIENT.CRT Convert the client certificate t

SSL uses public key encryption technology (RSA) as the encrypted communication protocol between the client and the server when transmitting confidential data. OpenSSL Overview Currently, one of the most popular Authentication servers is the

It is widely used in various network applications. In the DTLS relay Implementation of

In April 9, TechCrunch, a tech blog website, reported that OpenSSL, a security protocol used by many enterprises and services to encrypt data, had a vulnerability in the past two years, hackers can exploit this vulnerability to steal 64 KB data from the server memory. The 64 KB data volume is not large, but hackers can exploit this vulnerability repeatedly to steal data multiple times and obtain users' encryption keys to decrypt sensitive data. Ev

{Code ...} I wrote a Python version using pyopenssl, as follows: {code ...} the problem mainly lies in x509data. How can I get the data in x509data? In Python, this is an object. function getCertId($cert_path) { $pkcs12certdata = file_get_contents ( $cert_path ); openssl_pkcs12_read ( $pkcs12certdata, $certs, SDK_SIGN_CERT_PWD ); $x509data = $certs ['cert']; openssl_x509_read ( $x509data ); $certdata = openssl_x509_parse ( $x509data ); $cert_id = $certdata ['serialNumber'];

This time to everyone to bring PHP does not compile installation OpenSSL extension implementation, PHP does not compile installation of the OpenSSL extension of the attention to what, the following is the actual case, together to see. When using the RSA algorithm in PHP, you need to call the Openssl_get_publickey method, but you also need to compile the OpenSSL
