This is where I dump small tools I build while learning new things.

Tools

File	Language	What it does
portscanner.py	Python	Scans TCP ports on a host
filehashgenerator.go	Go	Computes MD5, SHA-1, SHA-256, SHA-512 hashes for a file
dnslookup.py	Python	Performs DNS lookups for a domain
caesar.rb	Ruby	Encodes and decodes text using a Caesar cipher
counter.rb	Ruby	Counts lines, words, and characters in a file
passwordgenerator.py	Python	Generates secure random passwords

usage

Each tool is self-contained. Run with --help for usage details.
