Currently, gnark-crypto implements twisted Edwards arithmetic in affine coordinates and projective coordinates. We should implement extended coordinates as they allow faster arithmetic out-circuit.

This is a good first issue for someone who wants to get into OSS/TPM development.

We need a simple example to show TPM signature verification.

We already have examples for TPM2_Quote and TPM2_GetTime that can be used to generate signed TPM blob(data).

Details:

• Both TPM2_Quote and TPM2_GetTime produce similar output using TPM2B_ATTEST and TPMT_SIGNATURE structures.
• The TPMT_SIGNATU

What is wrong?

Really small nit. primitives is incorrectly spelled primatives in py_ecc.bls.g2_primatives

Hi! Looks promising. I tried it out as :

git clone https://github.com/cubbit/enigma.git 
cd enigma 
npm install

everything seem to go alright until the install runs node-gyp rebuild :

make: Entering directory `/var/www/html/valg/lib/enigma/build'
  ACTION Prepare dependencies /var/www/html/valg/lib/enigma/dependencies
Error: Unsupported arch: ia32 - linux

How easy would it be to change the library to have versions of the encode and decode functions where the payload JSON was provided / returned just as the JSON text?

There are other good JSON generation / parsing libraries available, and some people may wish to use them to generate or process the payload, rather than the built in claim processing.
