Brute force + hand-solve for 5CTF's Discorderly2 challenge. It's not pretty but it does the job.

python3 brute_solve.py

https://www.nom.fish/write-up/5charlie-ctf-disorderly2/

My "nicer" solve for 5CTF's Discorderly2 challenge. Mostly just a quick fun refresher on C and applying a different technique.

$ gcc -Wall -pedantic -o setsolve setsolve.c
$ python3 c_solve.py jmrxy

OWA S/MIME Decryption with Ubuntu & Firefox

NOTE: This is still being refined.
I'm not sure if I had any pre-existing packages that were necessary or if all of the ones I list are necessary.
If you have any feedback, please let me know.
Thank you!
