1. Clone your fork:

git clone git@github.com:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

1. Convert our ".jks" file to ".p12" (PKCS12 key store format):
 
keytool -importkeystore -srckeystore oldkeystore.jks -destkeystore newkeystore.p12 -deststoretype PKCS12
 
1.1. List new keystore file contents:
 
keytool -deststoretype PKCS12 -keystore newkeystore.p12 -list
 
2. Extract pem (certificate) from ".p12" keysotre file:

1. Convert our ".jks" file to ".p12" (PKCS12 keystore format): 
keytool -importkeystore -srckeystore { java-keystore.jks } -destkeystore { pkcs12-keystore.p12 } -deststoretype PKCS12

2. Extract pem (certificate) from ".p12" keystore file: 
openssl pkcs12 -nokeys -in { pkcs12-keystore.p12 } -out { certificate-chain.pem }

3. Extract unencrypted key file from ".p12" keystore file: 
openssl pkcs12 -nocerts -nodes -in { pkcs12-keystore.p12 } -out { unencrypted-key.key }
