* TROUSERS_0_3_14 - Changes to support OpenSSL 1.1.0 - Removed some warnings for proper builds - Changes to allow building on OS X - Fixed memory leaks - Fixed failure to recognize connections from localhost over IPv6 - Fixed for an exploitable local denial of service in tcsd * TROUSERS_0_3_13 - Changed exported functions which had a name too common, to avoid collision - Assessed daemon security using manual techniques and coverit - Fixed major security bugs and memory leaks - Added debug support to run tcsd with a different user/group - Daemon now properly closes sockets before shutting down * TROUSERS_0_3_12 - Added new network code for RPC, which supports IPv6 - Users of client applications can configure the hostname of the tcsd server they want to connect through the TSS_TCSD_HOSTNAME env var (only works if application didn't set a hostname in the context) - Added disable_ipv4 and disable_ipv6 config options for server * TROUSERS_0_3_11 - Fix build process for distros - License was changed from GPL to BSD - Many bugfixes - updated man pages

\fBTspi_Hash_Sign\fR signs the hash data of an
object with a given signing key. The data must be set at the hash
instance associated with \fIhHash\fR by calling
\fBTspi_Hash_SetHashValue\fR or \fBTspi_Hash_UpdateHashValue\fR. The
\fBTspi_Hash_Sign\fR method allocates a memory block for the
\fIprgbSignature\fR data. This memory must be released using

.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.
.SS pulSignatureLength
Receives the length of the signature data returned at the parameter
\fIprgbSignature\fR on successful completion.
.SS prgbSignature
Receives a pointer to the signature data on successful completion.

\fBTspi_Hash_Sign\fR returns TSS_SUCCESS on success, otherwise one
of the following values is returned:
\fIhKey\fR is not a valid handle.

An internal SW error has been detected.

One or more parameters is bad.

Hash length is inconsistent with hash algorithm.

Hash object has no internal hash value.

The hash algorithm identifier is not set.


\fBTspi_Hash_Sign\fR conforms to the Trusted Computing Group Software
Specification version 1.1 Golden
