How do I generate a RSA key?

Generating an SSH key

  1. Open the PuTTYgen program.
  2. For Type of key to generate, select SSH-2 RSA.
  3. Click the Generate button.
  4. Move your mouse in the area below the progress bar.
  5. Type a passphrase in the Key passphrase field.
  6. Click the Save private key button to save the private key.

How do I generate a private key from a certificate?


  1. Open the command line.
  2. Create a new private key in the PKCS#1 format. openssl genrsa -des3 -out key_name .key key_strength. For example: openssl genrsa -des3 -out private_key.
  3. Create a certificate signing request (CSR). The request is associated with your private key and is later transformed into a certificate.

How do I create a key file?

To create a KeyFile:

  1. Download OpenSSL and extract the files to your machine.
  2. Open the Command Prompt and navigate to your bin folder of your OpenSSL directory, for example, …/Openssl/bin.
  3. Run the command: openssl rand -base64 756 > For example: openssl rand -base64 756 > c:\openSSL\key.

How long does it take to generate a RSA key?

Creating New Private Keys A constructor that creates a new random RSA private key with a modulus of length bits. RSA key generation is relatively slow, and can take an unpredictable amount of time. Generating a 2048 bit RSA key might take 5 to 10 seconds on a slow machine like a Raspberry Pi 2.
