👉 Archspies are a type of cryptographic technique that uses a series of key pairs to encrypt and decrypt data. An archspi, for example, would be used in a digital signature scheme where each signer is assigned an unique public key. In cryptography, an archspi is often used as the basis for other types of encryption schemes such as RSA or AES. It's also used in a variety of applications, including biometric authentication and smart cards.
