CreaSign provides a security mechanism which prevents an untrusted code from misusing a component. All methods that access local resources (file system, private keys, etc) are protected by this mechanism. The mechanism is activated when a CreaSign component is instantiated from an untrusted code such as a webpage.
An untrusted code can call the SetSafetyOptions method to present an evidence of trust. If the evidence is valid, the code gets unrestricted access to all the functionality provided by CreaSign.
This does not apply to CreaSignWeb object. CreaSignWeb requires web site to be in Trusted Site list. Take a look at instructions on how client can add your web site to his trusted site list.
