CSP Functions

The following table describes the CSP functions. Each function in the table corresponds directly to a CryptoAPI function with the suffix Crypt instead of CP. For example, CPCreateHash is the same as CryptCreateHash.

Function Description
CPAcquireContext Acquires a handle to a particular key container within the CSP.
CPCreateHash Creates a hash object and returns a handle to it.
CPDecrypt Decrypts a section of ciphertext using the specified encryption key.
CPDeriveKey Creates a key from a password.
CPDestroyHash Destroys a hash object.
CPDestroyKey Destroys a key.
CPDuplicateHash Makes an exact copy of a hash object and the state the hash is in.
CPDuplicateKey Makes an exact copy of a key, including the state of a key.
CPEncrypt Encrypts a section of plaintext using the specified encryption key.
CPExportKey Transfers a key from the CSP into a key BLOB in the application's memory.
CPGenKey Creates a random key.
CPGenRandom Generates random data.
CPGetHashParam Retrieves a hash object parameter.
CPGetKeyParam Retrieves a key's parameters.
CPGetProvParam Retrieves attributes of the CSP.
CPGetUserKey Gets a handle to the key exchange or signature key.
CPHashData Hashes a block of data and adds it to the specified hash object.
CPHashSessionKey Hashes a session key and adds it to the specified hash object.
CPImportKey Transfers a key from a key BLOB to a CSP.
CPReleaseContext Frees the handle acquired by CPAcquireContext.
CPSetHashParam Sets a hash object parameter.
CPSetKeyParam Specifies a key's parameters.
CPSetProvParam Sets specific attributes of a CSP.
CPSignHash Signs the specified hash object.
CPVerifySignature Verifies a digital signature.
