I have seen a code in one site which could convert sha256 hash to base64 with C language but when I tested it, it didn't work at that time so I ignored. I need it now but unfortunately I can't find it through the net anymore. I want to ask if there is such code in C or other languages that can convert sha256 hash to base64?

I'm looking to convert audio, images, video to base64 in c++, and through many searches on the web I've only seem to come up with string > base64.
When I view a .mp3 file for example, there are many characters there that are not available to be used in my string to encode.
[URL] ....
I have this code set up in my project, and all I want is to be able to give the location of any file and have it encode (could just encode to a string, I can handle writing it to a file), and then give a location to put the decoded file as well.
I'm not sure exactly where to even start.
I am trying to generate a sha256 hash with std string, but i can't get this incomplete code puzzle to work [URL] .....
void main() {
string pbData1 = "HELLO";
BYTE* pbOutputBuffer;
CryptoPP::SHA256().CalculateDigest(pbOutputBuffer, (byte*)pbData1.c_str(), pbData1.size());
cout << pbOutputBuffer;
}
my problem is converting 'const char *' to 'const byte *' ..etc
is it possible to write a code that can crack the sha256 hash when you know the form of password? for example the password form is *-********** which is 12-13 characters long and the first char is one number from 1 to 25, second one is hyphen and in each char from the third one to the end, you can put a...z, A...Z and 0...9 and after guessing each pass, the code convert the pass to sha256 and see whether the result hash is equal to our hash or not and then print the correct pass. I know all possible numbers is a big number ((26+26+10)^10) but I want to know that: 1- Is it possible to write such code? 2-if yes, is it possible to run whole code in less than one day(because I think it takes a lot of time to complete the whole code)? 3-Since I can't ask you to write a code for me, how and where can I ask for this code? 4-if no, is it possible to write such code in other programming languages?

I tried CRC 16, 32 and with polynomial 0xEDB88320L, and with all these tries, I cannot find the correct checksum, it is my main problem.I don't want C++ code source, but I am searching for the method or algorithm to find it. If you want to know, this string in base64 contains an string compressed in zip, which contains an UTF16 XML. I want to modify information, and modify Adobe Projet (prproj)

View 3 Replies View RelatedI was assigned a problem involving using buffer overflow to access a different function than I was supposed to. I was able to figure out how to modify the point in stack that I need to change using a printf statement, however what doesn't make sense is that when I use the input "AABBCCDDEEFFGGx86x64x00x00" the stack changes to 78363878 I looked up the ascii codes and I assume that it's not converting x86, but using the input x86 instead.
