Full disclosure, I perfectly get the theory, and came to the same conclusion myself, but I have absolutely no clue about the technical implementation :D

Ok here we go: 

Empty vault file name: emptyvault.cryptoSafe
Empty vault file content: (one line, no trailing newline character) 62eIxonP+2mIsrhfIn0IzQ==
Empty vault password: foobar 

ETH vault file name: ETHkey.cryptoSafe
ETH vault file content: (one line, no trailing newline character) RJ+YWtuyOoLnnOpOdmj43+hwO5cquMsSO3f/OiQfINofM+c0JVbIyUTQg3St+1Ue09QiZKlNnCAmlPHq2wuI31QoZQ/KNKZT/VMLd3qYbkOv873HT4wsYeavSwOqrdVdxpEimkqgdDkGP7XHfeFUCv6+jXFZioiR8jYrgxA8fDQQ5C+YReuvfiqLGaVrC9ih58X8Q7NLxAlQTGSQvHgsZI6DNfAsXw3Zt++fIJh9bdLzHDEBF/pLp47zj132UOYr6TuufnnA+HeUISdk+xH6/w==
ETH vault password: foobar

Apparently the vault content is a concatenation of multiple informations: coin name, pub key, private key, seed and comment as shown on the last screen capture displayed on . I can't find in the code any information regarding that storage :(
Here are the info for the ETH vault: 

ETH vault coin name: ETH
ETH public key: 0x4ac97B48CbBF9D54AE1f07bF72b10F19eBE30BB1
ETH private key: a5f54b647905db05a82d523fe0027a5da9760c2e97e4124448896f7333cdf96f
ETH seed: (left blank)
ETH vault comment: (left blank)

thanks to 0 padding up to 32 chars, using password foobar in the app GUI gives the same result as foobar0000, foobar0000000000, foobar000000000000000, etc., this app is so nicely coded… :)
