TPMLIB_DecodeBlob(3) TPMLIB_DecodeBlob(3) NAME TPMLIB_DecodeBlob - Decode a base64-encode TPM blob SYNOPSIS #include <libtpms/tpm_types.h> #include <libtpms/tpm_library.h> TPM_RESULT TPMLIB_DecodeBlob(const char *buffer, enum TPMLIB_BlobType type, unsigned char **result size_t *result_len); DESCRIPTION The TPMLIB_DecodeBlob() function is used to decode a base64-encoded TPM state blob. The caller must pass what type of blob is expected to be de- coded and following that the function will look for the start and end mark- ers of the data. The following types of blobs are supported along with their start and end markers: BLOB_TYPE_INITSTATE '-----BEGIN INITSTATE-----' marks the beginning of the base64-encoded blob. '-----END INITSTATE-----' marks the end of the base64-encoded blob. This function is useful when passing state to the TPM inside the callback that is invoked to get the TPM's state blob. See TPMLIB_RegisterCall- backs(3). ERRORS TPM_SUCCESS The function completed successfully. TPM_SIZE The size of a requested buffer exceeds the limit or the system is out of memory. TPM_FAIL An error occurred while attempting to decode the blob.
