Rsa Key Generation In Javascript

RSA(Rivest-Shamir-Adleman) is an Asymmetric encryption technique that uses two different keys as public and private keys to perform the encryption and decryption. With RSA, you can encrypt sensitive information with a public key and a matching private key is used to decrypt the encrypted message. Asymmetric encryption is mostly used when there are 2 different endpoints are involved such as VPN client and server, SSH, etc.

Below is an online tool to perform RSA encryption and decryption as a RSA calculator.

For Java implementation of RSA, you can follow this article.

First, we require public and private keys for RSA encryption and decryption. Hence, below is the tool to generate RSA key online. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded.

Oct 05, 2007  Generating Keys. Generating public keys for authentication is the basic and most often used feature of ssh-keygen. Ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a good reason for using a shorter and less secure key.

By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format.

  1. Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub email address. $ ssh-keygen -t rsa -b 4096 -C 'youremail@example.com' This creates a new ssh key, using the provided email as a label. Generating public/private rsa key pair.
  2. An Online RSA Public and Private Key Generator. Sep 6 th, 2013. It then occurred to me (and a head slapped followed), that I have fairly recently published a library for Javascript RSA encryption which includes private and public key generation for RSA encryption. Not only that, but this is.
  3. Apr 19, 2016  This jsbn library was written using the raw variables to perform encryption. This is great for encryption, but most private keys use a Private Key in the PEM format seen below. 1024 bit RSA Private Key in Base64 Format.

RSA Encryption and Decryption Online

Below is the tool for encryption and decryption. Either you can use the public/private keys generated above or supply your own public/private keys.

Any private or public key value that you enter or we generate is not stored on this site, this tool is provided via an HTTPS URL to ensure that private keys cannot be stolen.

Usage Guide - RSA Encryption and Decryption Online

In the first section of this tool, you can generate public or private keys. To do so, select the RSA key size among 515, 1024, 2048 and 4096 bit click on the button. This will generate the keys for you.

For encryption and decryption, enter the plain text and supply the key. As the encryption can be done using both the keys, you need to tell the tool about the key type that you have supplied with the help of radio button. By default, public key is selected. Then, you can use the cipher type to be used for the encryption. The different cipger options are RSA, RSA/ECB/PKCS1Padding and RSA/ECB/OAEPWithSHA-1AndMGF1Padding. Now, once you click the encrypt button the encrypted result will be shown in the textarea just below the button.

Remember, the encrypted result is by default base64 encoded.

Similarly, for decryption the process is same. Here, you need to enter the RSA encrypted text and the result will be a plain-text. You have both options to decrypt the encryption with public and private keys.
