Library Functions Manual Tspi_Hash_VerifySignature(3) TCG Software Stack Developer's Reference NAME Tspi_Hash_VerifySignature - verify the hash value with a given signa- ture SYNOPSIS #include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_Hash_VerifySignature(TSS_HHASH hHash, TSS_HKEY hKey, UINT32 ulSignatureLength, BYTE* rgbSignature); DESCRIPTION Tspi_Hash_VerifySignature verifies the hash value of a given hash ob- ject with a given signature. In order to use this command, one must have a hash and a signature of the hash that one is trying to verify. The public key which corresponds to the private key used to sign the hash is also needed. PARAMETERS hHash The handle to the hash object instance whose hash value should be signed. hKey Handle to the key object which should be used for the signature verifi- cation. ulSignatureLength The length of the signature data provided at the parameter rgbSigna- ture. rgbSignature A pointer to the signature data. RETURN CODES Tspi_Hash_VerifySignature returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hKey is not a valid handle. TSS_E_INTERNAL_ERROR An internal SW error has been detected. TSS_E_BAD_PARAMETER One or more parameters is bad. TSS_E_HASH_INVALID_LENGTH Hash length is inconsistent with hash algorithm. TSS_E_HASH_NO_DATA Hash object has no internal hash value. TSS_E_INVALID_SIGSCHEME Invalid signature scheme.
