The private key is generated and saved in a file named 'rsa.private' located in the same folder. Generating the Public Key - Linux 1. Open the Terminal. Type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder. I am having problem finding a command that would generate a public and private key pair using OpenSSL. Could someone show me some example code of this in action. To sign an assembly with a strong name, you must have a public/private key pair. This public and private cryptographic key pair is used during compilation to create a strong-named assembly. You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an.snk extension. Dec 01, 2015 To generate a public/private key file on a Windows system: You will need to have OpenSSL installed. Create a new directory on your C drive and give it an appropriate name (i.e., Test). Open a Command Prompt window and go to the new directory. Opensslpkeynew generates a new private and public key pair. The public component of the key can be obtained using opensslpkeygetpublic. If you try and generate a new key using opensslpkeynew, and need to specify the size of the key, the key.
RSA keys
The JOSE standard recommends a minimum RSA key size of 2048 bits.
To generate a 2048-bit RSA private + public key pair for use in RSxxx and PSxxxsignatures:
Elliptic Curve keys
To generate an EC key pair the curve designation must be specified. Note thatJOSE ESxxx signatures require P-256, P-384 and P-521 curves (see theircorresponding OpenSSL identifiers below).
Common Name - The name through which the certificate will be accessed (usually the fully-qualified domain name, e.g., or mail.domain.com). Convert rsa key to pem. In the 'Distinguished Name Properties' window, enter the information as follows:.
Elliptic Curve private + public key pair for use with ES256 signatures:
Elliptic Curve private + public key pair for use with ES384 signatures:
Elliptic Curve private + public key pair for use with ES512 signatures:
PEM key parsing in Java
The BouncyCastle library provides a simpleutility to parse PEM-encoded keys in Java, to use them for JWS or JWE later.
Openssl Generate Private Public Key Pair List
For Maven you should include the following BouncyCastle dependencies (where1.52 is the latest stable version as of May 2015):
Example parsing of an PEM-encoded EC key in Java:
You need to programmatically create a public/private key pair using the RSA algorithm with a minimumkey strength of 2048 bits. The method you use to generate this key pair may differ depending onplatform and programming language.
Generating a public/private key pair by using OpenSSL library
The steps below are an example of the process for generating a public/private key pair for key exchange,using OpenSSL. To execute the following commands, you will need an OpenSSL runtime installed (whichyou can download and install from the OpenSSL website, or install one from your operating system’spackage management system).
Use Openssl To Generate Key Pair
- Generate an RSA key pair with a 2048 bit private key, by executing the following command:
'openssl genrsa - out private_key.pem 2048'
The following sample shows the command: - Extract the public key from the RSA key pair, by executing the following command:
'openssl rsa -pubout -in private_key.pem -out public_key.pem'
The following sample shows the command:A new file, public_key.pem , is created with the public key. - Follow the instructions in the next (Validating your private key) section to confirm that your key meets the required criteria.

Validating your private key
When a private key has been generated, you can use the following OpenSSL command to verify that theprivate key fits the required criteria.
Openssl Create Key Pair
- Execute the following command:
'openssl rsa -in private_key_sample.pem -text' - Verify that the first line of the output includes the private key strength:
Private Key: (2048 bit)
If the first line of output states “ unable to load Private Key ,” your private key is not a valid RSA private key.
