40bit decryption, pls help me to understand! - Joe_Ferro - 10-31-2016
Hi,
I've a decrying challenge and I hope hashcat is the right tool to calculate keys or
helps me to understand how the keys are calculator.
I've some 40bit seed's and key's (real pairs) , how can use this pairs to get the unknown keys?
Example:
S: 4F 74 B9 8B 06 K: A1 FC 0F 7F 3E
S: 90 CB 24 29 06 K: 1D E7 55 89 7E
S: 12 34 56 78 06 K: 6A AC 56 C6 78
S: 00 02 03 01 06 K: ?? ?? ?? ?? ??
Is it possible to generate the algorithm to generate the key's and if yes, how?
Thx in advance
Joe

No, you need the source code or reverse engineer the algorithm from the binary.
