Public-key cryptography, also known as asymmetric cryptography, is a fundamental concept in the field of cybersecurity. It involves the use of two distinct but mathematically related keys: a public key, which can be disseminated widely, and a private key, which must be kept confidential by the owner. The security of public-key cryptographic systems relies heavily

The RSA digital signature algorithm is a cryptographic technique used to ensure the authenticity and integrity of a message. Its security is underpinned by the mathematical principles of number theory, particularly the difficulty of factoring large composite numbers. The RSA algorithm leverages the properties of prime numbers and modular arithmetic to create a robust framework
