Text encryption and decryption tool

What's the encryption and decryption of text?

Text encryption (Encryption) is a process of converting (expressly) understandable information into uncomprehensible form (circular text) in order to prevent unauthorized persons from reading sensitive data. Decryption is its reverse process. In computer science and cryptography, these technologies are the basis for information security.

This tool provides a series of classic classical code algorithms. Classical passwords are usually based on replacement or migration operations, and although less secure in the face of modern computers, they are important in understanding encryption principles, learning the history of cryptography and simple covert communication.

Supported encryption algorithms

• Caesar Cipher: Most famous migration password. It moves each letter in the alphabet to a fixed position. For example, when offset 3 A Will become a D.
• ROT13: A special Caesar password with a fixed offset of 13 bits. ROT13 is again applied because of the 26 letters in the English alphabet , and then the original text is restored.
• Virginia Password (Vigenère Cipher): A multi-table replacement password, which determines the amount of each letter by using a keyword, is more difficult to break than a single replacement password.
• Atbash Cipher: An old replacement code. It flips the alphabet, which is A for Z, B for Y.
• Binary and hexadecimal: Although strictly encoding rather than encryption, they are often used to transform text into a computer-friendly bottom format, thereby changing the appearance.

Common application scene

The text encryption tool has many interesting uses in everyday life:

• Privacy protection: Send notes, links or small text in public or on non-safe channels (such as private social media letters) that do not want to be gleaned by others.
• Education and learning: Learning basic algorithms, discrete mathematics and the logic of data conversion in computer science.
• Decrypt game: Create and solve the puzzles in the escape of the secret room, Geochaching.
• Contents hidden: The government has been working to prevent the unwitting presence of spoilers in the press.

Security Warning: Do not use financial or highly sensitive data

Please note that the algorithms provided by this tool (e.g. Caesar or Virginia) are in the classical password category. These algorithms are very easily deciphered by violence or frequency analysis in the face of modern computing capabilities. ** The use of this tool for the encryption of payment codes, bank information, commercial secrets or any very high value data relating to the safety of life and property is strictly prohibited. ** For such data, please use a standard modern encryption library (e.g., AES-256 or RSA.
