Javascript Generate Rsa Key Pair
I need to know how to generate 'rsa' key-pair on the client-side using angular2. I need to generate private/public key pair and save the private key into database and want to use public key. JavaScript Generating RSA key pair and converting to PEM format Example In this example you will learn how to generate RSA-OAEP key pair and how to convert private key from this key pair to base64 so you can use it with OpenSSL etc. I need to generate a RSA key pair with Javascript. This key pair will be used for encrypting a one time blob of data (20-100kb), then discarded. This data can be reduced to a couple of hundred kb or less if I only encrypt data that needs to be secure and not other resources such as image files for the application. How to generate public/private key in C#. Asymmetric cryptography also known as public-key encryption uses a public/private key pair to encrypt and decrypt data. In.NET, the RSACryptoServiceProvider and DSACryptoServiceProvider classes are used for asymmetric encryption. I need to generate a 1024 bit RSA key for one time use (gets discarded after each run) and pass the public key to a remote client. The remote client expects the key to be 'in ASN.1 format as defined in x509'. (I know how to make the private key in the first place with openssl, and then how to extract the public key - both in ascii format. I need to know how to generate 'rsa' key-pair on the client-side using angular2. I need to generate private/public key pair and save the private key into database and want to use public key inside.
RSA Key Generator
This tool generates a RSA PEM key pair
Prerequisites:
- NodeJS:https://nodejs.org/en/download/
- GIT:https://git-scm.com/downloads
Install
Once you have installed NodeJS and GIT on your system, you can download and install this tool with the following commands:
git clone https://github.com/tevix/rsa-key-gen.git
cd rsa-key-gen
npm install
Usage
To generate a key pair run the following command:
node generate
The tool will generate two .pem files, one public key and one private key in the current directory:
Generate a RSA PEM key pair from pure JS
Usage

Performance
Performance greatly depends on the bit size of the generated private key. With 1024 bits you get a key in 0.5s-2s, with 2048 bits it takes 8s-20s, on the same machine. As this will block the event loop while generating the key,make sure that's ok or to spawn a child process or run it inside a webworker.
Pro Tip: authorized_keys
@maxogden found out how to use this module to create entries for the authorized_keys file:
API
keypair([opts])
Get an RSA PEM key pair.
opts can be
bits: the size for the private key in bits. Default: 2048.e: the public exponent to use. Default: 65537.

With npm do
Kudos
To digitalbazaar for theirforge project, this library is merely awrapper around some of forge's functions.
