Digital signatures in cryptography use mathematical algorithms to authenticate digital messages or documents. They ensure data integrity, non-repudiation, and authentication in online transactions.

Data Integrity: Verifies that the data has not been altered during transmission, ensuring its accuracy.

Non-Repudiation: Signers cannot deny their digital signature, providing evidence of their involvement in a transaction.

Authentication: Confirms the identity of the sender, preventing unauthorized access.

Digital signatures in cryptography use public-key cryptography, where each party has a public and private key pair. The sender signs the message with their private key, and the recipient verifies it with the sender's public key.

Security: Protects against tampering and unauthorized access, ensuring secure data exchange.

Efficiency: Streamlines authentication processes, reducing manual verification efforts.

Global Acceptance: Widely recognized and utilized in secure online transactions worldwide.

Digital signatures in cryptography are fundamental to ensuring secure and trustworthy online communications. By exploring their mechanisms, benefits, and common questions, we gain a deeper understanding of their role in modern cryptography and digital security.
