# Secure Two-party Threshold ECDSA from ECDSA Assumptions **IMPORTANT**: Version 0 of the protocol is experimental and not suitable for production use. It is kept here for backward compatability. We have added type conversion functions in the Version 1 package that can be used to migrate V0 data to V1 data types. Package dkls implements the 2-of-2 threshold ECDSA signing algorithm of [Secure Two-party Threshold ECDSA from ECDSA Assumptions](https://eprint.iacr.org/2018/499).
