Explain Encryption #478

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Hello,

first of all my english ist not so good but i will try to explain.

I'm intrested in the function of the encryption. I saw you used md5 for saving 
the passphrase. You used it a few times but how often?

For encryption you used AES CBC?

Did you encode the message befor?

Unencrypted I have this message:
76322f386430633866663037653464313733612f343662373664316233613564612f50494e472f2f

v2/8d0c8ff07e4d173a/46b76d1b3a5da/PING//Test notification�

Encrypted (passphrase: test), not the same notification, this:
2fcafaaa1c55fdb6541728ca1aca4596c18401b3a405ccbac2a5d57167b3f3b0a6eba9b02930edd0

I searched for documentation too. But found nothing. So I inspected the source 
code.

I wrote this wrapper which uses the Encryption.java file from oldsvn branch. It 
works for my (longer) passphrase but get an error with your example. Maybe it 
helps anyway.

Documentation is in the file.
