It is also possible to generate self-signed certificates. Keytool currently handles X.509 certificates. X.509 Certificates The X.509 standard defines what information can go into a certificate, and describes how to write it down (the data format). All the data in a certificate is encoded using two. You can generate a private key (and a self-signed certificate) by using the keytool -genkeypair command. For example: keytool -genkeypair -noprompt -alias self -keyalg RSA -keysize 2048 -sigalg SHA256withRSA -dname 'CN=hostname.example.com' -validity 365 -keypass password -keystore privatekey.jks -storepass password -storetype JKS.
To Use keytool to Create a ServerCertificate
Run keytool to generate a new key pair in the defaultdevelopment keystore file, keystore.jks. This exampleuses the alias server-alias to generate a new public/privatekey pair and wrap the public key into a self-signed certificate inside keystore.jks. The key pair is generated by using an algorithm oftype RSA, with a default password of changeit.

Keytool Generate Self Signed Certificate With Private Key Search
From the directory in which you want to create the key pair, run keytool as shown in the following steps.

- Generate the server certificate.Type the keytool command all on one line: Java aes 256 encryption example.When you press Enter, keytool prompts you to enterthe server name, organizational unit, organization, locality, state, and countrycode.You must type the server name in response to keytool’sfirst prompt, in which it asks for first and last names. For testing purposes,this can be localhost.When you run the example applications, the host (server name) specifiedin the keystore must match the host identified in the javaee.server.name property specified in the file tut-install/examples/bp-project/build.properties.
- License key generator software free download mp3. Export the generated server certificate in keystore.jks intothe file server.cer.Type the keytool commandall on one line:
- If you want to have the certificate signed by a CA, read the exampleat http://download.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html.
- To add the server certificate to the truststore file, cacerts.jks, run keytool from the directory where you createdthe keystore and server certificate.Use the following parameters:Information on the certificate, such as that shown next, will appear:
- Type yes, then press the Enter or Return key.The following information appears:
