Technical assignment Goal: Develop a program to find the XOR encryption key from an encrypted and unencrypted Lua file, as well as create a compiler and decompiler for Lua using the found key. Development stages Input data analysis: Obtain the encrypted and unencrypted Lua files. (Also an uncompiled and unencrypted LUA file) The source files may differ by no more than 5% Finding the XOR encryption key: Read both files byte by byte. Perform the XOR operation between the corresponding bytes of the encrypted and unencrypted files, considering possible differences in the files. Save the result as the encryption key. Compiler development: Create a program that takes a Lua file and an encryption key. Apply XOR encryption to each byte of the file using the key. Save the encrypted file. Decompiler development: Create a program that takes an encrypted Lua file and an encryption key. Apply XOR decryption to each byte of the file using the key. Save the decrypted file. Testing: Conduct testing on various Lua files to verify the correctness of the compiler and decompiler. Encrypted files for testing will be provided.

Здравствуйте. А какой бюджет?
-
Всё зависит от вас как бысто вы можете ето зделать
-
Сделать (если я правильно понял ТЗ) по прикидкам пару недель минимум, скорее всего с заботливо разложенными граблями и месяц. То есть собрать компилятор из имеющегося пару часов максимум, возня с XOR это на пару дней максимум чтобы проверить все варианты. А вот декомпилер - проблема. С ним больше всего возни и будет. И граблей там разложено наверняка не мало

За какую цену вы готовы ето зделать ?
