NAME
Tspi_Hash_Sign - sign the hash data of an object with a signing key 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_Sign(TSS_HHASH hHash, TSS_HKEY hKey, UINT32 pulSignatureLength, BYTE** prgbSignature); DESCRIPTION
Tspi_Hash_Sign signs the hash data of an object with a given signing key. The data must be set at the hash instance associated with hHash by calling Tspi_Hash_SetHashValue or Tspi_Hash_UpdateHash. The Tspi_Hash_Sign method allocates a memory block for the prgbSignature data. This memory must be released using Tspi_Context_FreeMemory. 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. pulSignatureLength Receives the length of the signature data returned at the parameter prgbSignature on successful completion. prgbSignature Receives a pointer to the signature data on successful completion. RETURN CODES
Tspi_Hash_Sign 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_HASH_NO_IDENTIFIER The hash algorithm identifier is not set. CONFORMING TO
Tspi_Hash_Sign conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO

NAME
Tspi_Hash_VerifySignature - verify the hash value with a given signature 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 object 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 verification. ulSignatureLength The length of the signature data provided at the parameter rgbSignature. 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. CONFORMING TO
Tspi_Hash_VerifySignature conforms to the Trusted Computing Group Software Specification version 1.1 Golden SEE ALSO
