A python script to generate a list of possible homoglyph domains of a given domain name. This may be useful to monitor for phishing sites when used in combination with certificate transparency or whois polling.

homoglyph-gen was developed using Python 3.7.2, other versions are untested, but will probably work though you may need to install additional dependencies.

• homoglyphs

This script will load all possible homoglyph categories and attempt to find all possible combinations. This may take a while and will probably eat a bit of memory in its current form.

# Display homoglyph domains for o-sp.com as UTF-8
