Stefan Berger 7d79ecd694 swtpm: Return TPM_FAIL if SWTPM_NVRAM_DecrytpData is called without key 
Return TPM_FAIL if SWTPM_NVRAM_DecryptData() is called without a key or
if an unhandle type of encryption mode is encountered. Previously this
function would return no error but also would not do any decryption if
no key was provided. Consequently, it would then also not return a byte
array with decrypted data which in turn could led to potential NULL
pointer accesses in subsequent calls. However, all current callers check
whether they have a valid key before they call this function. So the
change is primarily done for static analyzers, such as gcc -fanalyzer,
to ease code analysis.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.
