Pigpen Cipher

Tags

The Pigpen Cipher, also known as the Masonic Cipher or Freemason's Cipher, is a simple substitution cipher used for encoding secret messages. It has its roots in the ancient practice of symbolic writing and is often associated with Freemasonry, a fraternal organization known for its use of secret symbols and rituals.

PHP

Tags

PHP, which stands for Hypertext Preprocessor is a widely-used open-source server-side scripting language that was created by Rasmus Lerdorf in 1994. Initially developed for tracking visitors to his online resume, PHP quickly evolved into a powerful language for web development. It allows developers to create dynamic web pages and applications efficiently, making it one of the cornerstones of modern web development.

CHMOD: Understanding File and Directory Permissions

In Unix-like operating systems (such as Linux and macOS), CHMOD is a command used to change the file or directory permissions. Permissions control who can read, write, or execute a file or directory.

Permission Structure

Permissions are grouped into three categories:

Null Cipher

Tags

The Null Cipher, also known as the Null Encryption or Null Message, is a simplistic cryptographic technique where specific letters or symbols are deliberately left blank or null in a message. Instead of using complex algorithms or substitutions, the Null Cipher relies on the absence of characters to convey hidden information.

NATO

Tags

ORIGIN: International

It is a phonetic alphabet that uses 26 code words.

These words are used to ensure oral communication is clearly understood.

The NATO, North Atlantic Treaty Organization, phonetic alphabet became effective in 1956 and just a few years later became the established universal phonetic alphabet.

However, it took several adaptations before the version used today came into effect.

Morse

Tags

ORIGIN: USA

Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes or dits and dahs. Morse code is named after Samuel Morse, an inventor of the telegraph

Morse code is usually transmitted by on-off keying of an information-carrying medium such as electric current, radio waves, visible light, or sound waves. The current or wave is present during the time period of the dot or dash and absent during the time between dots and dashes

Map Cipher

Tags

The Map Cipher, also known as the Route Cipher or Matrix Cipher, is a method of encryption that involves rearranging characters of a message according to a predefined route or pattern on a grid or map. It is a type of transposition cipher, where the original letters of the plaintext are preserved, but their order is changed to create the ciphertext.

Keyboard Code

Tags

- Substitution Cipher

Keyboard Code, also known as Keyboard Cipher or Keyboard Encryption, is a simple and straightforward method of encrypting and decrypting messages using a keyboard layout as a reference. It is a type of substitution cipher, where each letter of the plaintext is replaced with a corresponding letter from the keyboard layout.

JavaScript

A Language for Web Interactivity

JavaScript, commonly abbreviated as JS, was developed by Brendan Eich at Netscape in 1995. Originally known as LiveScript it later adopted the name JavaScript to capitalize on the popularity of Java at the time. Unlike its namesake, JavaScript is a scripting language designed explicitly for client-side web development, enabling dynamic and interactive web experiences.

Java

The Language for Platform Independence

Java, a widely used and versatile programming language, was introduced by James Gosling and his team at Sun Microsystems in the early 1990s. Originally named Oak it later evolved into Java, with its first public release in 1995.
