You are a h4ck3r n00b: you "acquired" a bunch of password hashes, and you want to decipher them. Based on the length, you already guessed that they must be SHA-1 hashes. You also know that these are weak passwords: maximum 5 characters long and use only lowercase letters (a-z), no other characters.
Notes:
- pre-generating the full hash table is not advised, due to the time-limit on the CW platform
- there will be only a few tests for 5-letter words (hint: start from the beginning of the alphabet)
