Java Keytool Command

These commands allow you to generate a new Java Keytool keystore file, create a CSR, and import certificates. Any root or intermediate certificates will need to be imported before importing the primary certificate for your domain.

  • Generate a Java keystore and key pair

    keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -keysize 2048

  • Generate a certificate signing request (CSR) for an existing Java keystore

    keytool -certreq -alias mydomain -keystore keystore.jks -file 8gwifi.csr

  • Import a root or intermediate CA certificate to an existing Java keystore

    keytool -import -trustcacerts -alias root -file 8gwifiCA.crt -keystore keystore.jks

  • Import a signed primary certificate to an existing Java keystore

    keytool -import -trustcacerts -alias mydomain -file mydomain.crt -keystore keystore.jks

  • Generate a keystore and self-signed certificate  

    keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass password -validity 360 -keysize 2048

  • Check a stand-alone certificate

    keytool -printcert -v -file 8gwifi.crt

  • Check which certificates are in a Java keystore

    keytool -list -v -keystore keystore.jks

  • Check a particular keystore entry using an alias

    keytool -list -v -keystore keystore.jks -alias mydomain

  • Delete a certificate from a Java Keytool keystore

    keytool -delete -alias 8gwifi -keystore keystore.jks

  • Change a Java keystore password

    keytool -storepasswd -new new_storepass -keystore keystore.jks

  • Export a certificate from a keystore

    keytool -export -alias mydomain -file mydomain.crt -keystore keystore.jks

  • List Trusted CA Certs

    keytool -list -v -keystore $JAVA_HOME/jre/lib/security/cacerts

  • Import New CA into Trusted Certs

    keytool -import -trustcacerts -file /path/to/ca/ca.pem -alias CA_ALIAS -keystore $JAVA_HOME/jre/lib/security/cacerts

OpenSSL Commands

  • Generate a new private key and Certificate Signing Request
    openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privatekey.key
  • Generate a self-signed certificate 
    openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt
  • Generate a certificate signing request (CSR) for an existing private key
    openssl req -out CSR.csr -key privatekey.key -new
  • Generate a certificate signing request based on an existing certificate
    openssl x509 -x509toreq -in certificate.crt -out CSR.csr -signkey privatekey.key
  • Remove a passphrase from a private key
    openssl rsa -in privateKey.pem -out newprivatekey.pem
  • Convert a DER file (.crt .cer .der) to PEM
    openssl x509 -inform der -in certificate.cer -out certificate.pem
  • Convert a PEM file to DER
    openssl x509 -outform der -in certificate.pem -out certificate.der
  • Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM
    openssl pkcs12 -in keyStore.pfx -out keystore.pem -nodes

    You can add -nocerts to only output the private key or add -nokeys to only output the certificates.

  • Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12)
    openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile
