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

# Generate a 1024-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 4096 bits.
# Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.
# It takes a considerable amount of time and processing power to generate
# an 8192-bit key.
success = rsa.GenerateKey(1024)
if (success != true)
    print rsa.lastErrorText() + "\n";
    exit

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

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