Puzzle Codes to Crack¶
base64 usually ends with 0, 1, or 2 = signs
I strongly suggest piping to either "file" or "hexdump". Dumping random binary
data in your terminal isn't cool.
Tools¶
- hashcat
- xxd
- base64
- openssl enc
- hd
- gunzip
- xz
xfreerdp
is for RDP- ... What else?
Hashcat searching¶
When trying to find a hash, search for it.
The format is hashcat -m <somenumber>
where <somenumber>
is the type of hash
hashcat --help | grep AS-REP gives 18200
Stuff to look up¶
- Converting octal to decimal (or binary)

MP3 Challenge Cipher¶
First, convert the MP3 file to a WAV file.
ffmpeg -i silly-stderr-challenge.mp3 silly-stderr-challenge.wav
sox
.sox silly-stderr-challenge.wav -n spectrogram
The number of octets: 8 + 83 + 8
The first 8 bits: We use them to find the vertical position of the bits.
@arthvadrr We already use netpbm to convert to pgm. We have pgmtopbm.
@TrshPuppy Each letter is 800/99-ish pixels high.
