keytool

How do I import a .jks file into the java security's truststore? All the tutorial I'm seeing is using a ".crt" file. However, I only have the ".jks" file which is also the keystore I generated using the keytool command. Currently, I'm following this tutorial . I was able to generate a Java keystore and key pair and generate a certificate signing request (CSR) for an existing Java keystore, which is based on the tutorial. But I cannot import a root or intermediate CA certificate to an existing Java keystore, and import a signed primary certificate to an existing Java keystore, because it is

I am trying to re-sign some jars using the ant task 'signjar' however it's telling me "The signer certificate has expired." So I tried to re-generate the keystore hoping this would 'un-expire' it... keytool -genkey -keystore mykeystore -alias myalias but after entering the keystore password i get: "keytool error: java.lang.Exception: Key pair not generated, alias already exists" what am i doing wrong? do i need to delete the keystore to re-generate it or is there a simple way to refresh it so it's not expired? thanks. maaartinus You're mixing up the terms. A keystore contains keys, a key is

I have an SSL certificate in a Java keystore. It's going to expire in a week or so and I need to renew it. Can I reuse the previous CSR (which the CA still have) and then import the certificate using the import command or do I need to generate a new CSR? You can (if your CA doesn't check for public key reuse), but it's a bad security practice. The primary purpose of the validity period is to limit the time in which a certificate and associated private key is exposed to the possibility of being compromised. 来源： https://stackoverflow.com/questions/2787653/renew-certificate-with-java-keytool

I'm working on an app for a client that requires an SSL connection with an API. I've been provided with three files; a trust root certificate (.cer) file, an intermediate certificate (.cer) file and a signed response file. The instructions I've been given to install this relate to either IIS or the Java keytool program; I'm building the app in Ruby on Rails so neither is an option (as far as I am aware). The certificates are self-signed by the organisation who runs the API service and it appears I get given client certificates to mutually authenticate an https connection. I'm unsure how to use

I need to import a certificate for some maven repositories into the global keystore. The certificate file is named maven.crt so the command I am running is keytool -import -keystore $JAVA_HOME/jre/lib/security/cacerts -trustcacerts -alias maven -file maven.crt It asks me for password and then if I trust the certificate to which I answer yes This is the final output Certificate was added to keystore keytool error: java.io.FileNotFoundException: /usr/java/jdk1.7.0_40/bin/java/jre/lib/security/cacerts (Not a directory) I ran this command as root so I don't know why I am receiving permissions

I need a MD5 certificate to use in MapView in android. I have JDK 7 from Oracle installed. But running keytool -v -list -alias alias_name -keystore my-release-key.keystore is not giving me the result, instead it says to install openjdk. How to use the keytool in oracle jdk 7. And i am on ubuntu 12.04 64 bit. You can use keytool by doing this: cd /usr/lib/jvm/jdk1.7.0/bin ./keytool -v -list -alias alias_name -keystore my-release-key.keystore Keytool is not in your path by default, but it does not have to be in your path to be usable. Looks like your jdk installation has problems. Check to see
