Thanks for mentioning the actual problem, and what would come as a first thought in byte-string which is to just use the string constructor.

In this POST I'm going to suppose that we have found a possible SQL injection and we are going to discuss possible methods to confirm the SQL injection, recon the database and perform actions.
The CGI (Common Gateway Interface) defines a way for a web server to interact with external content-generating programs, which are often referred to as CGI programs or CGI scripts.
Как уже говорилось выше, после получения данных сервер должен преобразовать их и передать CGI программе. В стандартной спецификации CGI введенные клиентом данные при запросе GET помещаются сервером в переменную среды программы «QUERY_STRING».
SELECT * FROM Users WHERE username = 'Mike' AND password = '' OR '' = ''; Comment Out Query.
В случае CGI эта обработка осуществляется с помощью внешних программ и скриптов, обращение к которым выполняется через стандартизованный (см. RFC 3875: CGI Version 1.1) интерфейс — общий шлюз. Упрощенная модель, иллюстрирующая работу CGI
The Java platform provides two implementation of hashing functions: MD5 (produces 128-bit hash value), SHA-1 (160-bit) and SHA-2 (256-bit). This tutorial demonstrates how to generate MD5 and SHA hash values from String or file using Java.
In computing, Common Gateway Interface (CGI) is an interface specification that enables web servers to execute an external program, typically to process user requests. Such programs are often written in a scripting language and are commonly referred to as CGI scripts...
The purpose of this task to code and validate an implementation of the MD5 Message Digest Algorithm by coding the algorithm directly (not using a call to a built-in or external hashing library). For details of the algorithm refer to MD5 on Wikipedia or the MD5 definition in IETF RFC (1321).
