Concept:
Digital signatures are cryptographic tools used to authenticate the identity of the sender and ensure the integrity of the data being transmitted.
Step 1: Understanding asymmetric cryptography.
Digital signatures utilize a pair of keys: a private key, which is kept secret by the owner, and a public key, which is available to anyone.
Step 2: Identifying the underlying technology.
The process relies on "Public Key Infrastructure" (PKI) or public-key encryption. When a document is digitally signed, the sender uses their private key, and the recipient verifies it using the corresponding public key.
