You're apparently configured to use encryption or digital signatures with some folks, and Mail is asking permission to access Keychain for your private key — the type of encryption used here is sometimes called "asymmetric" or "public key", and it includes what's called a public key and a...
Private Key Encryption refers to a type of encryption system where both the sender and receiver use the same secret code to exchange private messages securely. It is also known as a "single-key" or "symmetric" system, where the same key is used for encryption and decryption. ...
Public key encryption is quite slow. To address this, messages arehashedand then encrypted with the private key, as opposed to encrypting the entire message to create the digital signature. For example, the signing software first creates a one-way hash of the digital document tha...
