Digital signatures are electronic equivalents of handwritten signatures that provide authentication, integrity, and non-repudiation for digital documents and transactions.
They are created and verified using the technology of cryptography, which involves mathematical algorithms to secure information.
Specifically, digital signatures use cryptographic techniques such as public key infrastructure (PKI), where a private key is used to create the signature, and a corresponding public key is used to verify its authenticity.
This process ensures that the signed document has not been altered and confirms the identity of the signer, making digital signatures a trusted method in electronic communications and e-commerce.
Conclusion:
Digital signatures are created and verified using cryptography, providing security and authenticity in the digital world.
