The following table describes the CSP functions. Each function in the table corresponds directly to a CryptoAPI function.

Function	Description
CPAcquireContext	Acquires a handle to a particular key container within the CSP.
CryptCreateHash	Creates a hash object and returns a handle to it.
CryptDecrypt	Decrypts a section of ciphertext using the specified encryption key.
CryptDeriveKey	Creates a key from a password.
CryptDestroyHash	Destroys a hash object.
CryptDestroyKey	Destroys a key.
CryptDuplicateHash	Makes an exact copy of a hash object and the state the hash is in.
CryptDuplicateKey	Makes an exact copy of a key, including the state of a key.
CryptEncrypt	Encrypts a section of plaintext using the specified encryption key.
CryptExportKey	Transfers a key from the CSP into a key BLOB in the application's memory.
CryptGenKey	Creates a random key.
CryptGenRandom	Generates random data.
CryptGetHashParam	Retrieves a hash object parameter.
CryptGetKeyParam	Retrieves a key's parameters.
CryptGetProvParam	Retrieves attributes of the CSP.
CryptGetUserKey	Gets a handle to the key exchange or signature key.
CryptHashData	Hashes a block of data and adds it to the specified hash object.
CryptHashSessionKey	Hashes a session key and adds it to the specified hash object.
CryptImportKey	Transfers a key from a key BLOB to a CSP.
CryptReleaseContext	Frees the handle acquired by CPAcquireContext.
CryptSetHashParam	Sets a hash object parameter.
CryptSetKeyParam	Specifies a key's parameters.
CryptSetProvParam	Sets specific attributes of a CSP.
CryptSignHash	Signs the specified hash object.
CryptVerifySignature	Verifies a digital signature.
