Gerenciando o certificado com o Java keytool:

Para gerar um certificado válido por 180 dias, usando algoritmo RSA::
keytool -genkey -keyalg RSA -alias livraria -keystore caelum_keystore.jks -storepass caelum -validity 180


Obs: Para usar com Tomcat usa a mesma senha para o keystore e para o certificado!


Para listar todo o conteudo do keystore:
