Ruby example code showing how to generate an RSA public/private key pair for encrypting.

Download Chilkat Ruby Library

require 'chilkat'

rsa = Chilkat::CkRsa.new()

success = rsa.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print "RSA component unlock failed" + "\n"
    exit
end

#  Generate a 1024-bit key.  Chilkat RSA supports
#  key sizes ranging from 512 bits to 4096 bits.
success = rsa.GenerateKey(1024)
if (success != true)
    print rsa.lastErrorText() + "\n"
    exit
end

#  Keys are exported in XML format:
publicKey = rsa.exportPublicKey()
print publicKey + "\n";

privateKey = rsa.exportPrivateKey()
print privateKey + "\n";
