To generate new 2048-bit RSA keys for console and/or agent communications If you are reusing an existing keystore that was used for either the Agent (port 443) or Console (port 4443) connector, you must first delete the existing key in the keystore by referencing its alias. In the past, we have generated keys with Java keytool, but we have been unable to find any information on generating a new, 2048-bit Diffie-Hellman parameter with Java keytool. Does anyone know how to do this or could point us in the right direction? To Use keytool to Create a Server Certificate. Run keytool to generate a new key pair in the default development keystore file, keystore.jks.This example uses the alias server-alias to generate a new public/private key pair and wrap the public key into a self-signed certificate inside keystore.jks. RSA is public-key encryption technology developed by RSA Data Security, Inc. Step 1 Open the command console on whatever operating system you are using and navigate to the directory where keytool.exe is located (usually where the JRE is located, e.g. C: Program Files Java jre6 bin on Windows machines).

Keyalg RSA -keystore keystore.jks -keysize 2048.
To Use keytool to Create a ServerCertificate
Run keytool to generate a new key pair in the defaultdevelopment keystore file, keystore.jks. This exampleuses the alias server-alias to generate a new public/privatekey pair and wrap the public key into a self-signed certificate inside keystore.jks. The key pair is generated by using an algorithm oftype RSA, with a default password of changeit.

When you press Enter, keytool prompts you to enterthe server name, organizational unit, organization, locality, state, and countrycode.
You must type the server name in response to keytool’sfirst prompt, in which it asks for first and last names. For testing purposes,this can be localhost.
When you run the example applications, the host (server name) specifiedin the keystore must match the host identified in the javaee.server.name property specified in the file tut-install/examples/bp-project/build.properties.
Export the generated server certificate in keystore.jks intothe file server.cer.
Type the keytool commandall on one line:
If you want to have the certificate signed by a CA, read the exampleat http://download.oracle.com/javase/6/docs/technotes/tools/solaris/keytool.html.
To add the server certificate to the truststore file, cacerts.jks, run keytool from the directory where you createdthe keystore and server certificate.
Use the following parameters:
Information on the certificate, such as that shown next, will appear:
Type yes, then press the Enter or Return key.
The following information appears:
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.
How To Generate Rsa Key
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.
By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 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.
This tool provides flexibility for RSA encrypt with public key as well as private key along with RSA decrypt with public or private key.

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.
