Libtpms-based TPM emulator with socket, character device, and Linux CUSE interface.
80d7bb488c
Extend the --print-capabilities option to also report supported RSA
key sizes. Only the TPM 2 may support anything else than 2048 bit RSA
keys, so we only consult 'swtpm socket --tpm2 --print-capabilities'
and grep for 2048 and 3072 key sizes and report them.
If nothing is found, nothing is reported, as before, and 2048 bit RSA
keys should be assumed.
'swtpm_setup --tpm2 --print-capabilities' may now show the following:
{
"type": "swtpm_setup",
"features": [
"cmdarg-keyfile-fd",
"cmdarg-pwdfile-fd",
"tpm2-rsa-keysize-2048",
"tpm2-rsa-keysize-3072"
]
}
Also adjust a test case to use a regular expression for matching
against an expected string that may nor may not have rsa-keysize
verbs.

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/.
Please consult the Wiki for information about swtpm:
