Check > options->keyhandle when ASN.1 is loaded. No that's not right. keyhandle must be specified for the old format, because it's just the two private/public blobs and doesn't know it's parent. Since tpm2_key_decode() always places the ASN.1 parent into options->keyhandle, the proposed new code is fully redundant (options- >keyhandle must be non zero if the ASN.1 parsed correctly) but it loses the check that the loader must specify it for the old format. What the comment above the code you removed means is that the keyhandle must be non zero here, either extracted from the ASN.1 for the new format or specified on the command line for the old. James
