- OpenSSL provides two command line tools for working with keys suitable for Elliptic Curve (EC) algorithms: openssl ecparam openssl ec The only Elliptic Curve algorithms that OpenSSL currently supports are Elliptic Curve Diffie Hellman (ECDH) for key agreement and Elliptic Curve Digital Signature Algorithm (ECDSA) for signing/verifying.
- $ begingroup$ I don't watch videos, but IF they're talking about TLS-formerly-SSL (and protocols layered on it like HTTPS) it is now fairly common to use elliptic Diffie-Hellman with 'ephemeral' keypairs (generated during the handshake, used once and destroyed) for the actual key agreement, and authenticate it with elliptic DSA using a long-term key in a certificate.

Dec 28, 2013 Pingback: Generating ECDSA certificate and private key in one step DL-UAT Philippe Leothaud August 20, 2015 at 13:11. Hi Guy, Thanks for the tip. Key generator for wingeeker tool. I had some problems with the -paramenc explicit option though: when you use it to generate the keypair openssl server side will not be able to pick a cipher suite from the ones presented by the client and the connection is therefore not established.

Project description
A lightweight and fast pure Python ECDSA
Overview
We tried other Python libraries such as python-ecdsa, fast-ecdsa and other less famous ones, but we didn't find anything that suited our needs. The first one was pure Python, but it was too slow. The second one mixed Python and C and it was really fast, but we were unable to use it in our current infrastructure, which required pure Python code.
For this reason, we decided to create something simple, compatible with OpenSSL and fast using elegant math such as Jacobian Coordinates to speed up the ECDSA. Starkbank-ECDSA is fully compatible with Python2 and Python3.
Installation
To install StarkBank`s ECDSA-Python, run:
Curves
What Is Public Key
We currently support
secp256k1
, but it's super easy to add more curves to the project. Just add them on curve.py
Speed
We ran a test on a MAC Pro i7 2017. The libraries were run 100 times and the averages displayed bellow were obtained:
Library | sign | verify |
---|---|---|
python-ecdsa | 121.3ms | 65.1ms |
fast-ecdsa | 0.1ms | 0.2ms |
starkbank-ecdsa | 4.1ms | 7.8ms |
Our pure Python code cannot compete with C based libraries, but it's
6x faster
to verify and 23x faster
to sign than other pure Python libraries.Sample Code
How to sign a json message for Stark Bank:
Simple use:
OpenSSL
This library is compatible with OpenSSL, so you can use it to generate keys:
Ecdsa Private Public Key Generation Openssl Update
Create a message.txt file and sign it:
To verify, do this:
Ecdsa Key Generation
You can also verify it on terminal:
NOTE: If you want to create a Digital Signature to use with Stark Bank, you need to convert the binary signature to base64.
You can do the same with this library:
