Secure Sensitive Data Sharing Using RSA and ElGamal Cryptographic Algorithms with Hash Functions

With the explosion of connected devices linked to one another, amount transmitted data grows day by day, posing new problems in terms information security, such as unauthorized access users’ credentials and sensitive information. Therefore, this study employed RSA ElGamal cryptographic algorithms with application SHA-256 for digital signature formulation enhance security validate sharing Security is increasingly becoming a complex task achieve. The goal be able authenticate shared function algorithms. methodology involved use C# programming language implementation using hash signature. experimental result shows that algorithm performs better than during encryption verification processes, while decryption generation process.
