Problems with decryptFile #3

Closed egarpor closed 5 years ago

egarpor commented 7 years ago

I am having troubles running the decryptFile utility. Seems like is missing some dependency on the Janino library?

Here is what I did:

$ java -jar sanitizer-0.13.jar decryptFile -vault /Users/Eduardo/Cryptomator_vault/
# Cryptomator vault sanitizer v0.13 #

Required key length not supported means that JCE is not installed which is needed for 256-bit keys.

Check out this guide on how to install JCE.

OK, so indeed the JCE was missing - I overlooked that part in the README. Thanks for pointing it out. But I still not able to decrypt a single file:

$ java -jar sanitizer-0.13.jar decryptFile -vault /Users/Eduardo/Cryptomator_vault/
# Cryptomator vault sanitizer v0.13 #

I did a check and it complains about the Janino library as well:

$ java -jar sanitizer-0.13.jar check -vault /Users/Eduardo/Cryptomator_vault/ -deep
# Cryptomator vault sanitizer v0.13 #

Vault password:

Done.

Is that because I also need to install Maven 3?

Closed due to inactivity. Just retried decryptFile and it should work. I noticed in your log messages that you have to specify the complete path of the output when it's asking for Enter absolute path of decrypted output. E.g., /Users/.../Desktop is not enough, you have to specify the output filename as well like /Users/.../Desktop/foo.
