(Ruby) Load PEM Public/Private Key into RSA Object

Demonstrates how to load a PEM key into the Chilkat RSA object.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

success = false

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

rsa = Chilkat::CkRsa.new()

# First demonstrate importing a PEM public key:
publicKeyPem = "PEM public-key data goes here"
pubkey = Chilkat::CkPublicKey.new()

success = pubkey.LoadFromString(publicKeyPem)
if (success == false)
    print pubkey.lastErrorText() + "\n";
    exit
end

success = rsa.UsePublicKey(pubkey)
if (success == false)
    print rsa.lastErrorText() + "\n";
    exit
end

# Demonstrate importing a PEM private key:
privateKeyPem = "PEM private-key data goes here"
privkey = Chilkat::CkPrivateKey.new()

# If the private key PEM is protected with a password, then 
# call LoadEncryptedPem.  Otherwise call LoadPem.
success = privkey.LoadPem(privateKeyPem)
if (success == false)
    print privkey.lastErrorText() + "\n";
    exit
end

success = rsa.UsePrivateKey(privkey)
if (success == false)
    print rsa.lastErrorText() + "\n";
    exit
end

print "OK!" + "\n";
