Secure Text Transfer Using Doubly Encrypted Chat Application Based on Cloud

Abstract

One of the most important ways to preserve information security is to use cryptographic techniques. It provides digital signature, authentication, secret sub-storage, system security, and other capabilities in addition to keeping the information confidential. As a result, the encryption and decryption solution can secure information secrecy, as well as information integrity and certainty, to avoid tampering, forgery, and counterfeiting. The security of encryption and decryption algorithms is determined by the algorithm's internal structure and mathematical rigour, as well as the key secrecy. The key in the encryption algorithm plays a crucial role; if the key is released, anybody may use the encryption system to encrypt and decrypt data, rendering the encryption process ineffective. As a result, the encryption and decryption solution can secure information secrecy, as well as information integrity and certainty, to avoid tampering, forgery, and counterfeiting. The security of encryption and decryption algorithms is determined by the algorithm's internal structure and mathematical rigour, as well as the key secrecy. The key in an encryption algorithm plays a critical role; if the key is released, anybody may use the encryption system to encrypt and decrypt data, rendering the encryption technique ineffective. As a result, throughout the encryption and decryption process, the type of data you pick to be a key, how you disseminate the private key, and how you preserve both data transmission keys are all critical considerations.
