Abstract
Mechanisms are provided for transferring sensitive information, such as cryptographic keys, between entities. Particularly, a device is provided with a user input connected directly to a secure element. The device enables a user to enter sensitive information in the user input which is then passed directly to the secure element without traversing any other element such that the secure element can encode and/or encrypt the sensitive information. Once the sensitive information has been encoded and/or encrypted by the secure element, the now secure sensitive information can be shared with other entities using familiar and popular, yet relatively unsecure, transfer methods.
