 LIBRARY
   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 API PARAMETERS
   CCHandle (input)
           The handle that describes the context of this cryptographic
           operation used to link to the CSP-managed information.

   ClearBufs (input)
           A pointer to a vector of CSSM_DATA structures that contain
           the data to be operated on.

   ClearBufCount (input)
           The number of ClearBufs.

   CipherBufs (output)
           A pointer to a vector of CSSM_DATA structures that contain
           the results of the operation on the data.

   CipherBufCount (input)
           The number of CipherBufs.

   bytesEncrypted (output)
           A pointer to uint32 for the size of the encrypted data in
           bytes.

   RemData (output)
           A pointer to the CSSM_DATA structure for the remaining cipher
           text if there is not enough buffer space available in the
           output data structures.

 SPI PARAMETERS
   CSPHandle (input)
           The handle that describes the add-in cryptographic service
           provider module used to perform calls to CSSM for the memory
           functions managed by CSSM.

   Context (input)
           Pointer to CSSM_CONTEXT structure that describes the attributes
           with this context.

   Privilege (input)
           The export privilege to be applied during the cryptographic
           operation. This parameter is forwarded to the CSP after CSSM
           verifies the caller and service provider privilege set includes
           the specified PRIVILEGE.

 DESCRIPTION
   This function encrypts all data contained in the set of input buffers
   using information in the context. The CSSM_QuerySize() function can be
   used to estimate the output buffer size required. The minimum number
   of buffers required to contain the resulting cipher text is produced
   as output. If the cipher text result does not fit within the set of
   output buffers, the remaining cipher text is returned in the single
   output buffer RemData.

   The CSP can require that the cryptographic context include access
   credentials for authentication and authorization checks when using a
   private key or a secret key.

 NOTES FOR API
   The output is returned to the caller either by filling the caller-
   specified buffer or by using the application's declared memory
   allocation functions to allocate buffer space. To specify a specific,
   preallocated output buffer, the caller must provide an array of one
   or more CSSM_DATA structures, each containing a Length field value
   greater than zero and a non-NULL data pointer field value. To specify
   automatic output buffer allocation by the CSP, the caller must provide
   an array of one or more CSSM_DATA structures, each containing a Length
   field value equal to zero and a NULL Data pointer field value. The
   application is always responsible for deallocating the memory when it
   is no longer needed. In-place encryption can be done by supplying the
   same input and output buffers.

 NOTES FOR SPI
   The output is returned to the caller as specified in Buffer Management
   for Cryptographic Services.

 RETURN VALUE
   A CSSM_RETURN value indicating success or specifying a particular
   error condition. The value CSSM_OK indicates success. All other
   values represent an error condition.

 ERRORS
   Errors are described in the CDSA technical standard.  See CDSA.
