Abstract
A browser includes modules to provide markup language applications with access to cryptographic functions executing in a secure zone. Non-secure operations associated with the cryptographic functions called by the markup language application may be executed in a virtual machine. Sensitive data such as cryptographic keys may be 'wrapped' or encrypted by the secure zone using a key. The encrypted sensitive data may then be stored in non-secure memory for further use. Upon request by the cryptographic functions, the encrypted sensitive data may be retrieved and decrypted with the secure zone for use.
