METHOD FOR ENCRYPTING AND DECRYPTING TEXT DATA

Abstract

ABSTRACT A method (100) for encrypting and decrypting text data. Further, the method comprising receiving plaintext input from a user via a graphical user interface (GUI). Further, the method (100) comprising the steps of selecting an encryption algorithm from a set of algorithms including a Caesar cipher and an Advanced Encryption Standard (AES). Further, the method (100) comprising the steps of applying the selected encryption algorithm to the plaintext input to generate ciphertext. Further, the method (100) comprising the steps of receiving the ciphertext input from the user for decryption and selecting the corresponding decryption algorithm. Further, the method (100) comprising the steps of applying the selected decryption algorithm to the ciphertext to recover the original plaintext and displaying it to the user via the GUI. <>

Specification

Description:FIELD OF THE DISCLOSURE
[0001] This invention generally relates to the field of data security and cryptography, and in particular relates to a method for encrypting and decrypting text data using multiple cryptographic algorithms, including traditional and modern techniques, to enhance the confidentiality and integrity of digital communications.
BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] The increasing reliance on digital communication and data storage has heightened concerns regarding the security and pri , Claims:1. A method (100) for encrypting and decrypting text data, the method comprising the steps of:
receiving plaintext input from a user via a graphical user interface (GUI);
selecting an encryption algorithm from a set of algorithms including a Caesar cipher and an Advanced Encryption Standard (AES);
applying the selected encryption algorithm to the plaintext input to generate ciphertext;
receiving the ciphertext input from the user for decryption and selecting the corresponding decryption algorithm; and
applying the selected decryption algorithm to the ciphertext to recover the original plaintext and displaying it to the user via the GUI.

2. The method (100) as claimed in claim 1, wherein the graphical user interface (GUI) includes error handling mechanisms to validate user inputs before processing the encryption and decryption operations.
