Can anyone help me out in understanding this code
# import os rotationMatrix1 = [7, 1, 5, 3, 0, 6, 2, 5, 2, 3, 0, 6, 1, 7, 6, 1, 5, 2, 7, 1, 0, 3, 7, 6, 1, 0, 5, 2, 1, 5, 7, 3, 2, 0, 6] rotationMatrix2 = [1, 6, 2, 5, 7, 3, 0, 7, 1, 6, 2, 5, 0, 3, 0, 6, 5, 1, 1, 7, 2, 5, 2, 3, 7, 6, 2, 1, 3, 7, 6, 5, 0, 1, 7] keyboardDict = { 2: '1', 3: '2', 4: '3', 5: '4', 6: '5', 7: '6', 8: '7', 9: '8', 10: '9', 11: '0', 16: 'q', 17: 'w', 18: 'e', 19: 'r', 20: 't', 21: 'y', 22: 'u', 23: 'i', 24: 'o', 25: 'p', 30: 'a', 31: 's', 32: 'd', 33: 'f', 34: 'g', 35: 'h', 36: 'j', 37: 'k', 38: 'l', 44: 'z', 45: 'x', 46: 'c', 47: 'v', 48: 'b', 49: 'n', 50: 'm' } def keyboardEncToAscii(inKey): out = "" for c in inKey: if c == 0: return out if c in keyboardDict: out += keyboardDict[c] else: return "" return out def decryptHash(hash, key, rotationMatrix): outhash = [] for i in range(0, len(hash)): outhash.append(((hash[i] << (rotationMatrix[7*key+i])) & 0xFF) | (hash[i] >> (8-rotationMatrix[7*key+i]))) return outhash print("") print("hexa decimal code") print("hexadecimal code from which the password can be calculated,") print("07088120410C0000") print("") print("Please enter the code: ") code = raw_input() hash = [] for i in range(1, len(code) // 2): hash.append(int(code[2*i]+code[2*i+1],16)) key = int(code[0:2], 16) % 5 password = keyboardEncToAscii(decryptHash(hash, key, rotationMatrix1)) if password == "": password = keyboardEncToAscii(decryptHash(hash, key, rotationMatrix2)) if password == "": print("The password could not be calculated.
