Definitions for "Key pair"
In public key cryptography, the entity's public key and its corresponding private key.
A private key and its corresponding public key in an asymmetric cryptosystem, keys which have the property that the public key can verify a digital signature that the private key creates.
An associated public and private key where the correspondence between the two are mathematically related, but it is computationally infeasible to derive the private key from the public key.
