KeyPurpose

Represents the various purposes or operations for which a cryptographic key can be used. Each enum value corresponds to a specific cryptographic operation or function.

Enumeration Members

DECRYPT

DECRYPT: DECRYPT

A key that can be used for decryption operations. This is typically associated with private keys in asymmetric encryption or shared keys in symmetric encryption.

---

ENCRYPT

ENCRYPT: ENCRYPT

A key that can be used for encryption operations. This could be a public key in asymmetric encryption or a shared key in symmetric encryption.

---

SIGN

SIGN: SIGN

A key that can be used for creating digital signatures. This is typically associated with private keys in asymmetric cryptography.

---

VERIFY

VERIFY: VERIFY

A key that can be used for verifying digital signatures. This is typically associated with public keys corresponding to the private keys used for signing.

---

WRAP

WRAP: WRAP

A key that can be used for wrapping (encrypting) other keys. Key wrapping is a method of securing cryptographic key material during transmission or storage.

---

UNWRAP

UNWRAP: UNWRAP

A key that can be used for unwrapping (decrypting) wrapped keys. This is the reverse operation of key wrapping, used to recover the original key material.

---

DERIVE

DERIVE: DERIVE

A key that can be used in key derivation functions. These functions derive one or more secret keys from a secret value such as a master key, password, or shared secret.
