NAME

sec_psm_decrypt_data —  Decrypt data that was encrypted with a public key mechanism. This routine is not available in the DCE binary code.  It is provided in DCE source for use by vendors. 

Synopsis

error_status_t sec_psm_decrypt_data(
sec_psm_handle_t psm_handle,
unsigned32 ∗kvno,
sec_pk_algorithm_id_t ∗encryption_alg_id,
sec_pk_usage_flags_t key_usage,
sec_pk_encrypted_t ∗cipher_data,
sec_pk__gen_data_t ∗clear_data,
error_status_t ∗status);

Parameters

Input

psm_handle
A pointer to an opaque handle to the personal security mechanism context. Use sec_psm_open()  to obtain the handle. 

kvnoThe unsigned 32-bit version number of the key in which the data is encrypted. 

encryption_alg_id
The ASN.1 DER-encoded object ID of the encryption algorithm, such as RSA, used to encrypt the data.

key_usageA sec_pk_usage_flags_t that contains the usage flag for the private key to be used for this operation. 

cipher_data
A pointer to a sec_pk_data_t that contains the ASN.1 DER-encoded data to be decrypted. 

Output

clear_dataA pointer to the decrypted data. 

statusA pointer to the completion status.  On successful completion, the routine returns error_status_ok.  Otherwise, it returns an error. 

Description

The sec_psm_decrypt_data() routine decrypts data that was encrypted with a public key mechanism.  The encryption_alg_id parameter specifies the encryption algorithm used.  This routine allocates memory for the returned decrypted data.  Call the sec_pk_data_free() routine to deallocate that memory.
