Apache implements https certificate key verification-Linux Enterprise Application-Linux server application information. The following is a detailed description. Build basic Apache services and access them properly. 1. Install the mod_ssl module to allow Linux to support SSL: Yum install mod_ssl-y 2. Create a certificate and key file: Cd/etc/pki/tls/certs Make httpd. crt // The Name Of The certificate file. Do not change the extension. At last, two fil

1. Install the ssl module # Yum-y install mod_ssl 2. Tell apache which website is to Use https, that is, to build a website. It can also be the same as what was previously set up in http. # Vi/etc/httpd/conf. d/ssl. conf DocumentRoot/var/www/test/html Servername www.bkjia.com 3. Create a certificate file # Cd/etc/pki/tls/certs [Root@www.bkjia.com] # make server. key ### generate a key file [Root@www.bkjia.com] # openssl rsa-in server. key-out server.

Python's PKCS7 encryption seems to be different, and the results are completely different. The code for PHP is as follows public static function Envelope ($data) {$Millisecond = Signenvelope::getmillisecond (); Save the source data file $dataFile = "./rsa/". $Millisecond. " Data.txt "; Save the signature file $signedFile = "./rsa/". $Millisecond. " Signed.txt "; After saving the signature base64 file $signedDataFile = "./rsa/". $Millisecond. " SignedData.txt "; File $envelopeFile = "./r

Self-built CA Based on OpenSSL and SSL certificate issuance For details about SSL/TLS, see the SSL/TLS principles.For more information about Certificate Authority (CA) and digital certificate, see OpenSSL and SSL digital certificate concepts. Openssl is a suite of open-source programs. It consists of three parts: one islibcryto, This is a general function of the encryption library, which implements a large number of encryption libraries; secondlibsslThis implements the ssl mechanism.

The main configuration file is in/etc/monit. conf (Fedora/CentOS/RHEL), or/etc/monit/monitrc (Debian/Ubuntu/Mint ). The Monit configuration file has two parts: Global and Services ).

Before that, we need to back up the current configuration file to ensure that the file can be restored after the problem is rectified. $ sudo cp /etc/proftpd.conf /etc/proftpd.conf.bak Then, we can use our favorite text editor to modify the configuration file. $ sudo vi /etc/proftpd.conf Then, append the following lines to the content we added in step 1.
