A CMD-File, thats convert a given File to a Base64-Code and write that to an other file. The File that should be encoded is submitted as command line parameter. So you can use the drap and drop function of Windows. The output file will be the same as the input but with the string ".base64" as suffix.

This gist show how to create a self signed certificate (bob) and use it to sign a other (alice). So a application only requires to know the public key of bob in order to trust alice, too. The Java Keytool is used.
rem # create a new self signed certificate insite the keystore bob.jks. This will act as issuer for the other certificate
rem # It is importent to add the extention BasicConstraints Certificate Authority (bc:c)
rem # Otherwise tools like the JVM will not accept other certificates issued by this
keytool -genkey -alias bob -keyalg RSA -keypass changeit -storepass changeit -keystore bob.jks -dname CN=bob -ext bc:c
rem # create a other self siged certificate for with we will create a Certificate Sign Request (CSR)
keytool -genkey -alias alice -keyalg RSA -keypass changeit -storepass changeit -keystore alice.jks -dname CN=alice
