Expose EK and standard template classes

[salrashid123]

Hi-

I'd like to reference standard ek templates but had to resort to digging them up from the 'internal/` package here

for 3.0.0-rc0 i'm using from tpm2_pytss.internal.templates import ek_rsa2048

for 2.3.0 i was using from tpm2_pytss.internal.templates import _ek

is there somewhere else i should acquire them (since i guess the internal prefix indicates its not intended for external use)?

Also, is there a timeline for the 3.0.0 release (i'll update my samples to not use the _ek reference then)?

thanks,

What is your use case for using the templates directly?
No release timeline for 3.0.0 at the moment, drained of time and energy from work and will probably be for a while.

i wanted to generate the primary directly like this

                nv, tmpl = _ek.EK_RSA2048
            
                primary1, ek_pub, _, _, _ = ectx.create_primary(
                    inSensitiveOwner, tmpl, ESYS_TR.ENDORSEMENT)

                ek_name = ek_pub.get_name()
                sess = setup_ek_session(ectx)
                rkeyLoaded = ectx.load(primary1, k.private, k.public,  session1=sess)

Could perhaps provide a function to just retrieve the template bases on name/enum

Yep, i just wanted a standard way to acquire these.

fwiw, i also find it useful to reference the "H-2" template described in pn pg 43 B.4.5 Template H-2: ECC NIST P256 (Storage). I use that to bootstrap PEM based keys described in the draft proposal ASN.1 Specification for TPM 2.0 Key Files and openssl

her'es the one i reference on my own pytss h-2
