Cryptanalysis of A Class of Ciphers Based on Linear Regression, Standard Deviation, and Chi-Squared Statistic

Because two different methods were attempted for the decryption process, two decryption files have been provided to showcase the different decryption methods used.

percentile_matching.py and regress_decrypt.py are the two main methods used to call upon their own decryption algorithm which work independently of one another.
