Combolist decrypt

[doomcode]

I want to decrypt a user:hash combolist in a result of user:pass.
Basically i want to replace the found lines and remove the others.
Example:

Flexu88:[redacted]
to:
Flexu88:word 
Or even Flexu88:[redacted]:word

[Xanadrel]

Read the rules.
Don't post hashes.
Do your own research.
