Automatically try "well known" passwords

[mcpherrinm]

Many java trust stores are "protected" with the default password changeit. Password protection often provides little value when the files are protected, perhaps in a secrets management system.

Other passwords I have seen from a github search for "keytool storepass" and we could guess:

changeit changeme keystore CHANGE ponies ez24get storepass Storepass password passphrase secret 123456
