Typogenerator: a typosquatting generator in Golang

A Golang typosquat generator utilizing various strategies to generate potential variants of a string. Some strategies are similar to those utilized by dnstwist. This library is not intended to be a complete port of dnstwist and may include additional strategies.

Usage

See files under cmd/ for example usage.

Fuzzing Algorithms (strategies)

1. Addition - Addition of a single character to the end of a string
2. BitSquatting - Generates a string with one bit difference from the input
3. DoubleHit - Addition of a single character that is adjacent to each character (double hitting of a key)
4. Homoglyph - Substituiton of a single character with another that looks similar
5. Hyphenation - Addition of a hypen - between the first and last character in a string
6. Omission - Removal of a single character in a string
7. Prefix - Addition of predefined prefixes to the start of a string
8. Repetition - Repetition of characters in a string (pressing a key twice)
9. Replace - Replacement of a single character that is adjacent to each character (pressing wrong key)
10. Similar - Replacement of a single character that looks the same. This is a subset of Homoglyph but is language specific.
11. SubDomain - Addition of a period . between the first and last character in a string
12. Transposition - Swapping of adjacent characters in a string
13. VowelSwap - Swapping of vowels in string with all other vowels

Languages

The following strategies are language dependent:

1. DoubleHit
2. Replace
3. Similar

Supported languages include:

1. English
2. French
3. German
4. Spanish
