How to create a RSA Key pair

3Commas now supports using RSA keys to create signed API requests.

All you need to do is generate an RSA Key pair and then only provide the public key on 3Commas.

Generate Keys via Command Line

You can use command line to create RSA Key pair

1

Generate Private Key

Run this command to generate a 4096-bit private key:

openssl genrsa

2

Save Private Key

Output the private key to a file, such as private.pem. You can adjust the key length and/or output file name as needed:

openssl genrsa -out private.pem 2048

3

Generate Public Key

To generate the public key from the private key, run this command:

openssl rsa -in private.pem -pubout -out public.pem

4

View Public Key

Run this command to view the public key:

cat public.pem

This public key needs to be registered on 3Commas.

Binance RSA Key Generator

You can use official Binance RSA key pair generator

Go to the official [RSA Keys Generator](https://github.com/binance/asymmetric-key-generator/releases) website to download and install the latest version of the generator.

Online RSA Key Generator

You can use an online RSA key pair generator, but we don't recommend this method due to security concerns.

For example: https://cryptotools.net/rsagen

You need to choose 2048 or 4096 key length for RSA key pair.
