/*
* sha1.c
*
* Description:
* This file implements the Secure Hashing Algorithm 1 as
* defined in FIPS PUB 180-1 published April 17, 1995.
*
* The SHA-1, produces a 160-bit message digest for a given
* data stream. It should take about 2**n steps to find a
* message with the same digest as a given message and
* 2**(n/2) to find any two messages with the same digest,
* when n is the digest size in bits. Therefore, this
* algorithm can serve as a means of providing a
* "fingerprint" for a message.
*
* Portability Issues:
* SHA-1 is defined in terms of 32-bit "words". This code
* uses <stdint.h> (included via "sha1.h" to define 32 and 8
* bit unsigned integer types. If your C compiler does not
* support 32 bit unsigned integers, this code is not
* appropriate.
*
* Caveats:
* SHA-1 is designed to work with messages less than 2^64 bits
* long. Although SHA-1 allows a message digest to be generated
* for messages of any number of bits less than 2^64, this
* implementation only works with messages with a length that is
* a multiple of the size of an 8-bit character.

//
// Some background: This app is linked with /subsystem:windows flag,
// which is the only way to avoid a console when the program is
// double-clicked from Windows Explorer. The problem with this is if
// the user starts the program from cmd.exe, the output is not shown
// anywhere. Generally there is one simple solution for console only
// apps: The /subsystem:console flag, but it shows a console when the
// program is started from Windows Explorer (anyway we could call
// FreeConsole(), but the console is visible some milliseconds which
// is not an expected behavior by normal Windows user).
//
// So this class tries to make some adjustments for apps linked with
// /subsystem:windows but that want to display some text in the
// console in certain cases (e.g. when --help flag is specified).
//
// Basically it tries to redirect stdin/stdout handles so the end-user
// can have the best of both worlds on Windows:
// 1) If the app is executed with double-click, a console isn't shown.
// (Because the process was/should be linked with /subsystem:windows flag.)
// 2) If the app is executed from a process like cmd.exe, the output is
// redirected to the cmd.exe console.
//
// In the best case, the application should work as a Unix-like
// program, blocking the cmd.exe in case 2, but it cannot be
// possible. The output/input is deattached as soon as cmd.exe knows
// that the program was linked with /subsystem:windows.
