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