Vigenère-Cipher-Decrypter is a tool that attempts to decrypt certain data encrypted by the Vigenère cipher. This tool can decrypt Vigenère cipher with and without Key

vegenere.py is the python3 file for decrypting the cipher

The encrypted data is decrypted by frequencies of letters observed and the key length is detected by peaks observed in the encrypted data and its shifts.

indexes from peakutils.peak for finding the length of key from peak values with recursive shifts in cipher.
