Of course it would be best if the hash format would indicate which AES key size was used, but again, as said above, it might not be possible to detect this with axcrypt2john.py (but maybe there is some way, dunno, also see: ). If we would implement this in hashcat, we probably would add 2 separate hash types "AxCrypt 2 AES-128" and "AxCrypt 2 AES-256" and the user must select one (they should either know the algorithm itself, or at least if they used the paid version etc). Following is the example of generating an AES encrypted password and decrypt an AES encrypted password. Advanced Encryption Standard (AES) is a symmetric encryption algorithm. my perl scripts from the forum post above should clearly show that the algorithms are different and therefore it's currently not cracking. You can decrypt a file online without a key if you have the right tool. The cost factor doesn't matter at all (well, only for how slow it is, but not if something is crackable or not). In the forum post I also mentioned that it might or might not be possible to detect if the file uses AES-128 or AES-256 from the file metadata alone (it might be the case that you need to enter a password and the software simply tests both until one succeeds or both fail, this is just an assumption but the AxCrypt spec PDF file hints to it that the cipher is not known). Yeah, the only problem is that JTR doesn't support AES-128 for AxCrypt files (which is actually the default one for the free version as far as I can tell). Preferred vector width: char 1, short 1, int 1, long 1 Native vector widths: char 1, short 1, int 1, long 1 It can decrypt files and show passwords stored in your account, but it cant encrypt files. If we want to decrypt this file, we will have two options, either click on Open. Decryption was also easy and straightforward as you only click the. The app functions, but its more of a reference than anything else. When we have encrypted it, it will appear in the list of recent files. Platform #0 name: NVIDIA CUDA, version: OpenCL 1.2 CUDA 10.1.152 After installation, you just click right click on the file and select Encrypt using AxCrypt. Once I realised that, I tried to create multiple accounts with different passwords and I was not able to crack any of them. I can assure that the correct password is in the file /tmp/axcrypt.txt used as a wordlist I double checked and I am able to decrypt it using the normal AxCrypt GUI and works even in a PC with no AxCrypt installed but using AxCryptBruteforcer, so the account is not logged in.Įdit: I am able to crack the test.axx file however that is the only one. I also tried to remove the filename before the hash, nothing changed.
