I was recently in a meeting where a person needed to generate a private andpublic key for RSA encryption, but they were using a PC (Windows). This is somethingthat is easily done via a terminal using ssh-keygen on Mac and Linux, however on Windows…this tool is not easily accessible to the non-technical person.

Can I generate a new private key for my SSL certificate? Since a public key with the additional information (i.e., domain name and administrative contact information) must be signed by a trusted certificate authority in order to make it applicable and legitimate for securing communication with your server, it wouldn’t make much sense if we.

It then occurred to me (and a head slapped followed), that I have fairly recentlypublished a library for Javascript RSA encryption which includes private andpublic key generation for RSA encryption. Not only that, but this is allavailable online.

So, if anyone needs an online RSA key generator, look no further than http://travistidwell.com/jsencrypt/demo.

This directly maps to the Open Source GitHub repository found at https://github.com/travist/jsencrypt, soanyone can modify this website to make it better.

And here is an iframe of the RSA key generation tool.

In order to be able to create a digital signature, you need a private key. (Its corresponding public key will be needed in order to verify the authenticity of the signature.)

In some cases the key pair (private key and corresponding public key) are already available in files. In that case the program can import and use the private key for signing, as shown in Weaknesses and Alternatives.

In other cases the program needs to generate the key pair. A key pair is generated by using the KeyPairGenerator class.

In this example you will generate a public/private key pair for the Digital Signature Algorithm (DSA). You will generate keys with a 1024-bit length.

Generating a key pair requires several steps:

Create a Key Pair Generator

Elixir Generate Public And Private Key In Bitcoin

The first step is to get a key-pair generator object for generating keys for the DSA signature algorithm.

Elixir Generate Public And Private Key Authentication

As with all engine classes, the way to get a KeyPairGenerator object for a particular type of algorithm is to call the getInstance static factory method on the KeyPairGenerator class. This method has two forms, both of which hava a String algorithm first argument; one form also has a String provider second argument.

A caller may thus optionally specify the name of a provider, which will guarantee that the implementation of the algorithm requested is from the named provider. The sample code of this lesson always specifies the default SUN provider built into the JDK.

Put the following statement after the

line in the file created in the previous step, Prepare Initial Program Structure:

Initialize the Key Pair Generator

The next step is to initialize the key pair generator. All key pair generators share the concepts of a keysize and a source of randomness. The KeyPairGenerator class has an initialize method that takes these two types of arguments.

The keysize for a DSA key generator is the key length (in bits), which you will set to 1024.

The source of randomness must be an instance of the SecureRandom class that provides a cryptographically strong random number generator (RNG). For more information about SecureRandom, see the SecureRandom API Specification and the Java Cryptography Architecture Reference Guide .

The following example requests an instance of SecureRandom that uses the SHA1PRNG algorithm, as provided by the built-in SUN provider. The example then passes this SecureRandom instance to the key-pair generator initialization method.

Elixir generate public and private key pair

Some situations require strong random values, such as when creating high-value and long-lived secrets like RSA public and private keys. To help guide applications in selecting a suitable strong SecureRandom implementation, starting from JDK 8 Java distributions include a list of known strong SecureRandom implementations in the securerandom.strongAlgorithms property of the java.security.Security class. When you are creating such data, you should consider using SecureRandom.getInstanceStrong(), as it obtains an instance of the known strong algorithms.

Generate the Pair of Keys

The final step is to generate the key pair and to store the keys in PrivateKey and PublicKey objects.
