WebJun 16, 2024 · A digital signature is a form of cryptography that uses the public key infrastructure, or PKI, to securely transmit messages and authenticate senders. Digital signatures require both a public and a private key to be decrypted. The public key will be signed by a trusted CA and will need to match the private key. A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender (authenticity), and that the message was not altered in transit (integrity).
