Crypto protocol reverse engineering

We have device to which we would like to communicate. Device asks for special reply for its handshake question. Example below: Request A5 11 20 57 D3 AB 51 BE 51 BC B0 0D 09 67 8D 93 1B CB 49 A3 01 EB Response 95 73 6D D4 5C 30 71 97 6F 98 12 34 8B 03 C2 FF 0E 7E 41 50 7B A4 1C CF A1 9D 21 88 47 92 1D 96 7B 37 01 48 42 01 55 1E 99 00 11 78 DB 1B 3D F8 9C 91 D3 81 70 DD DD 6C E6 41 1E BF 69 AD 56 3F E2 D6 6B 7A A8 5B E9 D0 95 28 10 70 05 06 06 1A 4C C9 12 62 E0 17 EF 3A 85 86 31 54 F6 39 81 2C B5 31 91 9A 73 D1 F6 67 4F FF B2 5C 64 02 8E 1C 08 BE 28 C1 21 54 7E B5 0B 77 B4 5F 37 21 2F 50 D8 We need to get C/Python program which will generate proper response on request. More examples upon request.
