Tspi_E...ssBlob(3) TCG Software Stack Developer's Reference Tspi_E...ssBlob(3) NAME Tspi_EncodeDER_TssBlob - generate a DER encoded TSS blob. SYNOPSIS #include <tss/tspi.h> TSS_RESULT Tspi_EncodeDER_TssBlob(UINT32 rawBlobSize, BYTE* rawBlob, UINT32 blobType, UINT32* derBlobSize, BYTE* derBlob); DESCRIPTION Tspi_EncodeDER_TssBlob is used to generate a DER-encoded blob in accor- dance with the ASN.1 data definitions in the Portable Data section of the Trusted Computing Group Software Stack Specification Version 1.2. PARAMETERS rawBlobSize Size of the unwrapped blob. rawBlob Pointer to the unwrapped blob. blobType Type of blob being wrapped (refer to the TSS_BLOB_TYPE_* constants). derBlobSize Pointer to the size of the derBlob buffer. On input this parameter con- tains a pointer to the maximum size of the supplied derBlob buffer. On output this parameter contains a pointer to the actual size of the DER-en- coded blob. On input, if this parameter points to a value of 0, then this function will return the size of the buffer required to hold the DER-en- coded blob without writing to the derBlob buffer. Note: If the raw data blob length is less than 2^16 bytes then the DER-en- coding may add no more than 20 bytes. derBlob Pointer to a buffer to hold the DER-encoded blob. RETURN CODES Tspi_EncodeDER_TssBlob returns TSS_SUCCESS on success, otherwise one of the following values are returned: TSS_E_BAD_PARAMETER TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
