- Jun 19, 2010 Tools like in F5 load balancers generate.crt and.key files ( they basically use openssl ). Here.crt is the signed certificate from a CA and key contains the private key. These keys and certificates are in PEM format. – Open both the files in a notepad and copy the contents in it to a new notepad file and save it with extension.pem.
- Create PKCS 12 file using your private key and CA signed certificate of it. You can use openssl command for this. Create JKS file using keytool command. Step 3 (Optional). Changing the password of private key file in keystore. More details from here as well. Step 4 (Optional).

Jan 21, 2009 Requirement: Create JKS keystore and truststore out of certificate and private key files given in pem format. Try to open the certificate and key files and it contains ASCII text that starts with -BEGIN CERTIFICATE-, then it is in PEM format. Using keytool in java, when a keystore is created it already has the. A certificate.crt and privateKey.key can be extracted from your Personal Information Exchange file (certificate.pfx) using OpenSSL. Follow this article to create a certificate.crt and privateKey.key files from a certificate.pfx file.
To Generate a Certificate by Using keytool
By default, the keytool utility creates a keystorefile in the directory where the utility is run.
Before You Begin
To run the keytool utility, your shell environmentmust be configured so that the J2SE /bin directory is inthe path, otherwise the full path to the utility must be present on the commandline.
- Change to the directory that contains the keystore and truststorefiles.Always generate the certificate in the directory containingthe keystore and truststore files. The default is domain-dir/config.
- Generate the certificate in the keystore file, keystore.jks,using the following command format:Use any unique name as your keyAlias. Ifyou have changed the keystore or private key password from the default (changeit), substitute the new password for changeit.The default key password alias is s1as.A prompt appears that asks for your name, organization, and other information.
- Export the generated certificate to the server.cer file(or client.cer if you prefer), using the following commandformat:
- If a certificate signed by a certificate authority is required,see To Sign a Certificate by Using keytool.
- Create the cacerts.jks truststore file andadd the certificate to the truststore, using the following command format:If you have changed the keystore or private key password from the default(changeit), substitute the new password.Information about the certificate is displayed and a prompt appearsasking if you want to trust the certificate.
- Type yes, then press Enter.Informationsimilar to the following is displayed:
- To apply your changes, restart GlassFish Server. See To Restart a Domain.
