Perform a length extension attack on SHA256. Can someone help me find what I'm doing wrong?
I have performed the attack using this hash_extender and got the correct signature, but I'm getting the wrong answer when I try to perform the attack by modifying the original algorithm.

There are a lot of these types of tools already in the reverse engineering community (in order of lowest chance of breaking when you throw really weird stuff at it):
GEF: https://gef.readthedocs.io/en/master/
PWNDBG: https://github.com/pwndbg/pwndbg
PEDA: https://github.com/longld/peda
They also come with a slew of different features to aid in RE/exploit dev, but many of them are also useful for debugging really weird issues.

GDB PEDA not being used by default?
Did you follow the instructions? Step 2 adds PEDA to your ~/.gdbinit so it will/should load every time you open gdb. So if it doesn't work check your ~/.gdbinit file.
