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. Ruby

require 'chilkat'

success = false

rsa = Chilkat::CkRsa.new()

# Generate a 2048-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 8192 bits.
privKey = Chilkat::CkPrivateKey.new()
success = rsa.GenKey(2048,privKey)
if (success == false)
    print rsa.lastErrorText() + "\n";
    exit
end

# Get the private key in PKCS8 Base64 format
privKeyPkcs8Base64 = privKey.getPkcs8ENC("base64")

# The key in base64 format will start similar to this:
# MIIEvAIBADANBgkqhkiG9w0BA...
print privKeyPkcs8Base64 + "\n";
