Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

$rsa = New-Object Chilkat.Rsa

# Generate a 2048-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 8192 bits.
$privKey = New-Object Chilkat.PrivateKey
$success = $rsa.GenKey(2048,$privKey)
if ($success -eq $false) {
    $($rsa.LastErrorText)
    exit
}

# Get the private key in PKCS8 Base64 format
$privKeyPkcs8Base64 = $privKey.GetPkcs8ENC("base64")

# The key in base64 format will start similar to this:
# MIIEvAIBADANBgkqhkiG9w0BA...
