Accumulative homework assignments for the Information Security course during my time in Uni. Today marks the 5th anniversary for this little project! Here are some samples of usage and output:
After installing and navigating to the installation directory, one can simply run this:
python CipheringAlgos.py PLAIN_TEXT ALGORITHM_INDEX OPERATION_CODE KEY [OPTIONAL_PARAMETER]
1- PLAIN_TEXT a string of your choosing.
2- ALGORITHM_INDEX one of:
- 0 : Additive Cipher
- 1 : Multiplicative Cipher
- 2 : Affine Cipher
- 3 : Vigenere Cipher
- 4 : AutoKey Cipher
- 5 : Hill Cipher
- 6 : Playfair Cipher
- 7 : ADFGVX Cipher
3- OPERATION_CODE either enc or dec for encode and decode respectively.
4- KEY an integer key.
Affine takes 2 integer keys. Playfair takes a string key (and an optional second parameter to either use j, or i in processing). ADFGVX require 2 keys(strings but integers also work because in the end they are mapped to their numerical order in the alphabet)
5- [OPTIONAL_PARAMETER] Can be the optional parameter for Playfair or the second key for Affine/ADFGVX as explained in the previous section.
