A cryptographic key that is used with an asymmetric (public key) cryptographic algorithm and is associated with a private key. The public key is associated with an owner and may be made public. In the case of digital signatures, the public key is used to verify a digital signature that was generated using the corresponding private key.

A cryptographic key used with a public-key cryptographic algorithm that is uniquely associated with an entity and that may be made public. The public key has a corresponding private key. The public key may be known by anyone and, depending on the algorithm, may be used: 1. To verify a digital signature that is signed by the corresponding private key, 2. To encrypt keys that can be decrypted using corresponsing private key, or 3. As on of the input values to compute a shared secret during a key agreement transaction.

A cryptographic key used with a public-key (asymmetric-key) algorithm that is uniquely associated with an entity and that may be made public. In an asymmetric (public) key cryptosystem, the public key is associated with a private key. The public key may be known by anyone and, depending on the algorithm, may be used to 1. Verify a digital signature that is signed by the corresponding private key, 2. Encrypt data that can be decrypted by the corresponding private key, or 3. Compute a shared secret during a key-agreement process.

A cryptographic key used with a public-key cryptographic algorithm that is uniquely associated with an entity and that may be made public. In an asymmetric-key (public-key) cryptosystem, the public key has a corresponding private key. The public key may be known by anyone and, depending on the algorithm, may be used, for example, to: 1. Verify a digital signature that was generated using the corresponding private key, 2. Encrypt keys that can be decrypted using the corresponding private key, or 3. Compute a shared secret during a key-agreement transaction.

A cryptographic key used with an asymmetric-key (public-key) cryptographic algorithm that may be made public and is associated with a private key and an entity that is authorized to use that private key. Depending on the algorithm that employs the public key, it may be used to:
1. Verify a digital signature that is signed by the corresponding private key;
2. Encrypt data that can be decrypted by the corresponding private key; or
3. Compute a piece of shared data (i.e., data that is known only by two or more specific entities).
