Digital signatures explained - Asymmetric encryption
In simple terms, digital signatures are a way to verify the authenticity and integrity of digital documents or messages. They use cryptographic techniques to provide a secure and tamper-proof method of verifying the identity of the signer and ensuring that the content of the document has not been altered. Here's a simplified explanation of how digital signatures work: Signing process: The person or organization who wants to sign a document generates a unique pair of cryptographic keys: a private key and a corresponding public key. The private key is kept secret and should only be known by the signer. The document or message that needs to be signed is put through a mathematical function called a hashing algorithm. This function generates a fixed-size unique value, often referred to as a hash or digest, which is specific to the content of the document. The private key is then used to encrypt the hash of the document. This encrypted hash, along with the public key, is attached to the
