Filter impossible bigrams

[optimisticninja]

The following are impossible bigrams: ["JQ", "QG", "QK", "QY", "QZ", "WQ", "WZ"]

When permutations mode is implemented (fixing things like using NG where ING should be by permitting the plaintext to a list with possibilities for multi-character/bigram runes), if a candidate contains these, remove it from the list

[d4v1-sudo]

An idea for that:

IMPOSSIBLE_BIGRAMS = ["JQ", "QG", "QK", "QY", "QZ", "WQ", "WZ"]

def generate_permutations(plaintext):
    # ...
    permutations = [permutation for permutation in permutations if not any(bigram in permutation for bigram in IMPOSSIBLE_BIGRAMS)]

    return permutations

for later:

from itertools import permutations

IMPOSSIBLE_BIGRAMS = ["JQ", "QG", "QK", "QY", "QZ", "WQ", "WZ"]

def generate_permutations(plaintext):
    # generate all possible permutations of the input text
    perms = [''.join(p) for p in permutations(plaintext)]
    # filter
    filtered_perms = [perm for perm in perms if not any(bigram in perm for bigram in IMPOSSIBLE_BIGRAMS)]

    return filtered_perms

# just an example
plaintext = "ING"
permutations = generate_permutations(plaintext)
print(permutations)
