SYNOPSIS

CSSM_RETURN CSSMAPI CSSM_SignDataFinal
    (CSSM_CC_HANDLE CCHandle,
    CSSM_DATA_PTR Signature)

DESCRIPTION

This function completes the final stage of the sign data function.

PARAMETERS

CCHandle (input)

The handle that describes the context of this cryptographic operation used to link to the CSP-managed information.

Signature (output)

A pointer to the CSSM_DATA structure for the signature.

RETURN VALUE

A CSSM return value. This function returns CSSM_OK if successful, and returns an error code if an error has occurred.

ERRORS

CSSM__MANIFEST_ATTRIBUTES_NOT_FOUND

No capability attribute found in the Manifest.

CSSM__CONTEXT_FILTER_FAILED

CSSM__CSP_INVALID_DATA

Invalid output CSSM_DATA buffer.

CSSM__NOT_ENOUGH_BUFFER

The output buffer is not big enough.

CSSM__CSP_MEMORY_ERROR

Not enough memory to allocate.

CSSM__CSP_STAGED_OPERATION_UNSUPPORTED

Staged operation unsupported.

CSSM__CSP_STAGED_OPERATION_FAILED

CSSM__CSP_PRIKEY_NOT_FOUND

Cannot find the corresponding private key.

CSSM__CSP_PASSPHRASE_INVALID

Passphrase length error or passphrase badly formed.

CSSM__CSP_PASSPHRASE_INCORRECT

Passphrase incorrect.

CSSM__CSP_PRIKEY_ERROR

Error in getting the raw private key or private key storage error.

CSSM__CSP_NOT_ENOUGH_BUFFER

The output buffer is not big enough.

CSSM__CSP_GET_STAGED_INFO_ERROR

Comments

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, pre-allocated output buffer, the caller must provide an array of one or more CSSM_DATA structures each one 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 de-allocating the memory when it is no longer needed. If the CSSM_DATA_PTR parameter is NULL (that is, does not point to an array of CSSM_DATA structures) or the number of CSSM_DATA structures is specified as zero, the error code CSSM_CSP_INVALID_DATA_POINTER is returned.
