Generate Ecdsa Public Key From Private Key Online

I'd like to generate a private elliptic curve key from user input like pass phrase. Is the best way to do this with a key derivation function like PBKDF2? Is there a better way? Edit (based upon @poncho's questions) To be specific, this is for a Bitcoin ECC private key. The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. Here's an example: klar (11:39) ssh-keygen Generating public/private rsa key pair.

The ECDSA private key is a random integer. It is usually denoted as x in the libraries I work with. The public key is G ^ x, where G is the base point. So exponentiating a point by and integer results in a point. The resulting point from y = G ^ x is your public key. Generate an ECDSA SSH keypair with a 521 bit private key. Ssh-keygen -t ecdsa -b 521 -C 'ECDSA 521 bit Keys' Generate an ed25519 SSH keypair- this is a new algorithm added in OpenSSH. Ssh-keygen -t ed25519 Extracting the public key from an RSA keypair. Openssl rsa -pubout -in privatekey.pem -out publickey.pem.

A lightweight and fast pure python ECDSA library

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:

in the beginning of the filename as this is not a valid filename character.You will be prompted for the DN information. Enter the following:keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore yourdomain.jks'Yourdomain' is the name of the domain you are securing. Java generate csr. However, if you are ordering a Wildcard Certificate, do not include. Just fill in the details, click Generate, and paste your customized keytool command into your terminal.If you prefer to roll your own keytool commands to generate your CSR, just follow our old instructions below:Create a New Keystore.You will be using the keytool command to create your new key-CSR pairing.

Curves

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:

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:

Create a message.txt file and sign it:

To verify, do this:

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:
