+.SH "DESCRIPTION"
+.PP
+\fBTspi_Hash_VerifySignature\fR 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.
+
+.SH "PARAMETERS"
+.PP
+.SS hHash
+The handle to the hash object instance whose hash value should be signed.
+.SS hKey
+Handle to the key object which should be used for the signature verification.
+.SS ulSignatureLength
+The length of the signature data provided at the parameter \fIrgbSignature\fR.
+.SS rgbSignature
+A pointer to the signature data.
+
+.SH "RETURN CODES"
+.PP
+\fBTspi_Hash_VerifySignature\fR returns TSS_SUCCESS on success, otherwise
+one of the following values is returned:
+.TP
+.SM TSS_E_INVALID_HANDLE
+\fIhKey\fR is not a valid handle.
+
+.TP
+.SM TSS_E_INTERNAL_ERROR
+An internal SW error has been detected.
+
+.TP
+.SM TSS_E_BAD_PARAMETER
+One or more parameters is bad.
+
+.TP
+.SM TSS_E_HASH_INVALID_LENGTH
+Hash length is inconsistent with hash algorithm.
+
+.TP
+.SM TSS_E_HASH_NO_DATA
+Hash object has no internal hash value.
+
+.TP
+.SM TSS_E_INVALID_SIGSCHEME
+Invalid signature scheme.
+
+
+.SH "CONFORMING TO"
+
