# Check the alias
keytool -list -keystore ${MYKEY}.jks

# Export to PKCS12
keytool -importkeystore -srckeystore ${MYKEY}.jks -destkeystore ${MYKEY}.pkcs -srcstoretype JKS -deststoretype PKCS12 -alias ${MYALIAS}

# Convert to PEM

SSL Socket

import socket, ssl 

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

ssl_sock = ssl.wrap_socket(s, certfile="${MYKEY}.pem") 

ssl_sock.connect(('example.com', 443))

ssl_sock.send(bytes('test\n', 'UTF-8'))

ssl_sock.recv(512)

ssl_sock.close

s.close
