This is a question about using the OpenSSL libraries, further discussion 
should be on openssl-users; I've set 'reply-to' appropriately, but I 
don't know what the mailing list will do with it.

I don't know if or how it's related to your problem, but you have 
defined a 7 byte array as the passphrase then told the function to use 
64 bytes at that location. There's no saying what values the other 57 
bytes of the passphrase will have, assuming they're accessible at all.

More luck than good judgement I suspect.
