![]() That means it's at least more than a plain old 8-byte XOR cypher using a folded password. So the IV for the encryption routine is fixed as well.Īt least XORing blocks of encrypted binary nulls with two different keys didn't quickly reveal any obvious common bits, nor did encrypting two successive blocks that differed only by a single bit of plaintext. AAAAAAAA encoded in one file produces exactly the same results as AAAAAAAA encoded in another. (Please note that these are just example values with nice visual properties, and not the exact values I saw!)Īlso, the encryption is the same from file to file. If I learn what your first block means, I know the third block means exactly the same data. When I changed that to AAAAAAAAbbbbbbbbAAAAAAAA I saw the following encoding: 12345678abcdefgh12345678. It will encrypt to an 8-byte repeating block on the drive, like this: 123456781234567812345678 If you have a file containing AAAAAAAAAAAAAAAAAAAAAAAA Its biggest readily apparent weakness is that the encryption algorithm is running in ECB mode. It appears to be using a 64 bit block cypher (perhaps DES) which pretty much rules out any of the more modern encryption algorithms. I spent a little while analyzing the "CruzerLock" software that came with my Cruzer Mini USB drive.

The process for replacing a lost driving licence is different in Northern Ireland, where licences here are still made up of two parts: a plastic photocard and paper counterpart. If you find your old licence after applying for a replacement, you must send it to the DVLA: ![]() If you have lived at your current address for less than three years, you will need to provide past addresses covering this period.
