Go password guesser

This CLI tool allows to match password with brute force algorithm according to provided dictionary.
Algorithm is based on linear search O(n).
Application is leveraging goroutines to boost performance.
For 'all' option, each method is split into goroutines, and these are then split into smaller goroutines for each dictionary keyword.
Cracking supports many encryption types:
raw, MD4, MD5, SHA-1, SHA-226, SHA-256, SHA-384, SHA-512, AES.

Signature

To run the script you have to follow this command:

[program] [hash] [method] [filePath]

• program is a way you execute program i.e. go run . or main.exe
• hash is hashed or raw password i.e. myPassword or 7c6a180b36896a0a8c02787eeafb0e4c
• method is one of these: all, raw, MD4, MD5, SHA-1, SHA-226, SHA-256, SHA-384, SHA-512, AES (for AES you need to specify key in code)
• filePath is path to dictionary, i.e. passwords.txt. (one keyword per line)

Example

We know that password is encrypted with MD5 method and somehow we have passwords dictionary.

go run . 7c6a180b36896a0a8c02787eeafb0e4c MD5 passwords.txt

If password is stored in passwords.txt we will obtain this result:

Cracking process initialized ...
Password cracked succesfully:
password1

Another case:
We dont know encryption method and we only have encrypted keyword and passwords dictionary.

go run . 450ad03db9395dfccb5e03066fd7f16cfba2b61e23d516373714471459052ec90a9a4bf3a151e600ea8aaed36e3b8c21a3d38ab1705839749d130da4380f1448 all passwords.txt

If password is stored in passwords.txt we will obtain this result:

Cracking process initialized ...
Trying methods: raw, MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
Password cracked succesfully with SHA-512 method:
myPassword
