EsoCipher: An Instance of Hybrid Cryptography

Authors: Neel Adwani
Comments: 3 Pages.

This paper proposes a whole new concept in the field of Cryptography, i.e., EsoCiphers. Short for Esoteric Cipher, EsoCipher is an algorithm, which can be understood by a few, who have the knowledge about its backend architecture. The idea behind this concept is derived from esoteric programming languages, but EsoCiphers will be having a practical use in the future, as more research is done on the topic. Although the algorithm is quite simple to understand, the complexity of the output will indeed prove to be difficult to brute-force if a secret is embedded in it. It uses a hybrid cryptography-based technique, which combines ASCII, Binary, Octal, and ROT 13 ciphers. The implementation and similarity index has been provided to show that it can be implemented practically.

Python String Slicing

Authors: K. S. Ooi
Comments: 8 Pages.

Python slice syntax is nothing new. We find such syntax in other programming languages. However, string slicing in Python is usually covered briefly in standard references, Python textbooks as well as favorite websites. In this article, the author attempts to explore every nook and cranny of string slicing in Python. Besides proving a string slicing theorem, the author explores the limitation of string slicing expressed in everyday languages, the default values of all three arguments of the slice, the minimal string slice statement, the meaning of negative step, the influence of step on other two arguments, and two suggestions to correctly predict the substring of a slice.
