# 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.

# You now have the private key in an encrypted format,
# which may be (for example) saved to a database.
