README
PoC of two-party threshold ECDSA with secp256k1
===
This sofware is a NON-SECURE implementation of Gallois Field, Paillier, DSA, ECDSA,
and curve secp256k1 with an adapted scheme of "Two-party generation of DSA signatures"
by MacKenzie and Reiter.
This Python implementation is fully working playground for testing threshold ECDSA signature and
zero-knowledge proofs. `DO NOT USE THIS SOFTWARE IN PRODUCTION`.
## Run threshold DSA
./sdsa.py
## Run threshold ECDSA
./secdsa.py
Example of output:
S-ECDSA

Sig status: True
## Generate Keypair in DER-encoding
The `pem.py` file can produce DER-encoded keypairs for the threshold. Currently the result
is outputed in the console in binary format (bytes-array w/ lenght).
./pem.py
