Steps to generate self-signed PKCS#12 SSL certificate and export its keys:

1- Create PKCS#12 keystore (.p12 or .pfx file)

keytool -genkeypair -keystore myKeystore.p12 -storetype PKCS12 -storepass MY_PASSWORD -alias KEYSTORE_ENTRY -keyalg RSA -keysize 2048 -validity 99999 -dname "CN=My SSL Certificate, OU=My Team, O=My Company, L=My City, ST=My State, C=SA" -ext san=dns:mydomain.com,dns:localhost,ip:127.0.0.1

• myKeystore.p12 = keystore filename. It can with .pfx extension as well.
• MY_PASSWORD = password used for the keystore and the private key as well.
• CN = commonName, it will be shown as certiciate name in certificates list.
• OU = organizationUnit, department name for example.

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
gpg --gen-key
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null`

# check current keys:
gpg --list-secret-keys --keyid-format LONG

# See your gpg public key:
gpg --armor --export YOUR_KEY_ID
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)
