Cryptography Service Provider (CSP) API

CSP_GenerateKeyPair ()

Accepts as input a handle to a cryptographic context describing the generate key operation and attributes of each key in the new key pair. The keys are returned in CSSM_KEY structures.

CSP_GenerateRandom ()

Accepts as input a handle to a cryptographic context describing the generate random operation. The random data is returned in a CSSM_DATA structure.

CSP_WrapKey ()

Accepts as input a handle to a symmetric/asymmetric cryptographic context describing the wrap key operation and the wrapping key to be used in the operation, the key to be wrapped, and a passphrase (if required by the CSP) that permits access to the private key to be wrapped.

CSP_UnwrapKey ()

Accepts as input a handle to a cryptographic context describing the key unwrap operation, the wrapped key to be unwrapped, and a passphrase (if required by the CSP) that will be used to control access to the private key for the unwrapping operation.

CSP_DeriveKey ()

Accepts as input a handle to a cryptographic context describing the derive key operation and the base key that will be used to derive new keys.

CSP_GenerateAlgorithmParams ()

Accepts as input a handle to a cryptographic context describing an algorithm and returns a set of algorithm parameters appropriate for that algorithm.

CSP_QueryKeySizeInBits ()

Accepts as input a handle to a cryptographic context and the context containing the key. This function returns a pointer to a data structure containing the keysize and effective keysize in bits.

CSP_AssociatePublicKeyWithPrivateKey ()

Accepts as input a handle to a cryptographic context and a public and private key pair and associates the public key with the private key.

CSP_ObtainPrivateKeyFromPublicKey ()

Accepts as input a CSP handle and a public key. This function returns a pointer to the private key that is associated with the public key.
