Python handles the Java generated certificate process, as well as the public key private key encryption, plus signature verification, AES plus decryption (here is the RSA X509 EVP in the M2crypto library)Java generated JKS certificate Python cannot be directly used to convert to PEM format using the following commands

One: The package that needs to be included import java.security.*; import java.io.*; import java.util.*; import java.security.*; import java.security.cert.*; import sun.security.x509.* import java.security.cert.Certificate; import java.security.cert.CertificateFactory; Second: Read the certificate from the file Write the certificate in. KeyStore to the file using Keytool, and then read the

The last time and said GoDaddy health please certificate process and operation;Now because of using Incapsula protection to use to HTTPS, when adding a website needs a custom certificate, which needs to upload private key information, because the public key can be keytool generated, so need to export private key information;The steps to export are as follows:One: Install OpenSSL and Openssl-devel:Yum Instal

OrderThe first two of the basic concepts and composition are roughly said, today's article, mainly about how to use Java code to generate a CA certificate, as well as when generating certificates, you need to set some properties.BodyNonsense not much to say, directly on the content.Here is the Java API, and a third-party component,--BC, (bouncy Castle). A little

Compilation: Javac Installcert.javaRun: Java installcert URL to accessThe last side outputs:Enter certificate to add to trusted keystore or ‘q‘ to quit: [1]Enter 1 and then enter directly to generate a certificate named ' Jssecacerts ' in the appropriate directory. Copy the certificate to the $java_home/jre/lib/securit

Convert the Java Keytools certificate to Openssl PEM file or keytools to export the private key file, keytoolspem The process and operation of requesting a certificate from a Godaddy user was mentioned above; Because Incapsula is used for https protection, you need to customize the certificate when adding a website.

Note that when importing a certificate, verify that the imported JDK is the JDK that the current program is running in, and that the path is the JRE directory path under the JDK directory, not the JRE directory that is peer to the JDKFirst, you can put the certificate you need to import in the Keytool's sibling directory, and then execute the following command.　　Certifi
