Extract md5 hashes inside txt file to new txt file (one p

Recommended Posts

Hi, thx for reading this.

So yeah, I cannot program. :D

Never learned how, all dough i do understand some syntax from some languages.

I thought I could find a tool/program for his but I could not. I also searched the forums for a autoit script that I could easily adjust (no luck)

So here is my problem:

I have a 9 MB txt file.

I contains "Username" "Email" "MD5 hash"

between username and email there is a random number of spaces and tabs.

between email and md5 hash also. Sometime 1 space and sometimes up to 12 spaces.

I need to extract all the md5 hashes so that I have a new txt file with a hash on each line.

The way I should think a script/program should be able to do this is like this:

- Openfile

-Read the first character, if it's not hexadecimal skip to the next character (so only valid characters are 0123456789ABCDEF, the hexadecimal values are all in uppercase)

-if it's hexadecimal (0123456789ABCDEF) put a counter on 1 and read the next character. If the next character is hexadecimal put the counter on 2, if not reset the counter back to 0.

when the counter has reached 32, read the last 32 characters and put those on the first line of a new txt file.

Repeat till end of file and put the next 32 hexadecimal string on a new line in the new txt file.

This should work and I should get a new txt file whit a 32 characters hexadecimal string on each line. ;)

Problem is that I don't know how the program the above.

I know I could eventually figure it out after 3 hours of wiki reading and another 3 hours of trial and error.

But I think a good programmer could write this in a autoit script within 5 minutes. ;)

Any good programmers that want to help me out ? :)

Fact is, there are any number of ways tocomplete the task, each would need a true example of the file in question (not all of it)

First, most people will not just write the code for you as this is a help section, you will most likely be directed to rentacoder if you hae no desire to put in any effort.

I recommend tAKING A LOOK AT THE STRING FUNCtions , or maybe try a _fileReadToArray() on the file to see what that produces, since you dont mention if the file is one line of many etc...

One hash per line.

I am now trying to write a c++ program for it.

I got the code for reading and writing to files from an example and I am now figuring out the rest.

From your description there is no doubt the task is very easy.

The problem I have with your request is that I'd like to read a good reason to extract MD5 and store them separately. Your wording make it look like somehow suspicious.
