#  All Chilkat classes can be unlocked at once at the beginning of a program
#  by calling UnlockBundle.  It requires a Bundle unlock code.

#  Create a Fortuna PRNG and seed it with system entropy.
#  This will be our source of random data for generating the ECC private key.
fortuna = Chilkat::CkPrng.new()
entropy = fortuna.getEntropy(32,"base64")

#  Generate a random ECC private key on the secp256r1 curve.
#  Chilkat also supports other curves, such as secp384r1, secp521r1, and secp256k1.

# privKey is a CkPrivateKey
privKey = ecc.GenEccKey("secp256r1",fortuna)

#  Save the private key to PKCS8 encrypted PEM
#  (The private key can be saved in a variety of different formats. See the online reference documentation.)
