It involves using a private key to create a unique digital fingerprint of the data, which can then be verified using the corresponding public key. This helps ensure that the message has not been altered or tampered with during transmission. Digital signatures are commonly used in electronic transactions, contracts, and secure communications to provide assurance of the sender's identity and the message's integrity. **
