Cryptography is a way of encoding and decoding information to guarantee its confidentiality and protection from unauthorised individuals. Within the realm of digital security and cryptographic algorithms, digital signatures play a critical role in establishing trust. Analogous to a physical signature, digital signatures leverage cryptographic algorithms to generate a unique mathematical fingerprint linked to the message content. Though software implementations of cryptographic algorithms are possible with general-purpose processors which usually excel in typical applications, yet they lack efficiency in performing complex arithmetic calculations, particularly those employed in cryptography as they have a maximum word length of 64 bits. The current guideline for the key length in cryptographic systems like RSA and Diffie-Hellman is greater than 2048 bits.
