I had a bit of inspiration recently with Fermat’s Attack on RSA and
decided to make an RSA demonstrator. It shows all the steps in
performing an RSA encryption using 2 known primes. It might be useful
during a CTF when trying to determine small RSA keys by hand. I’ll
eventually post a follow up for implementing that attack for small p
and q.
A caeser cipher is a cipher that moves each letter by a fixed
offset. You'll see these as a common challenge in easier CTF events. So,
I wrote a tool to encode caeser ciphers and generic shift ciphers.

This application decodes a unicode string into it's character codes, and names. It's meant to come in handy with CTF events.
You enter your string in the form below and it will print out a table with the decode of it. I created it because I found
it really difficult to find a decent decoder that gave me the actual codes.
