This disclosure relates to the provision of cryptographic services to web browsers, and more specifically, to systems and methods for providing cryptographic results to a browser from a cryptographic device over a persistent peer-to-peer connection. A method for obtaining cryptographic services for a browser executing a webpage comprising the steps of establishing a persistent peer-to-peer connection over a wireless Internet Protocol communication network between the browser and a cryptographic device, in response to receiving user input to the webpage, transmitting, by the browser, data indicated by the user input over the persistent peer-to-peer connection to the cryptographic device, for cryptographic processing of the data by the cryptographic device using a cryptographic key stored on the cryptographic device to produce a cryptographic result, and receiving, by the browser, the cryptographic result over the persistent peer-to-peer connection from the cryptographic device, and providing the cryptographic result to the webpage.

Cryptographic services for browser applications

A method of allowing collaboration on an encrypted document stored in a cloud computing network, the encrypted document associated with a first user having a first user account in the cloud computing network, the method comprising: in response to a request from the first user to share the encrypted document, sending a link to a public network destination to a second user address of a second user; receiving a request via the link from an unconfirmed user to access the data in the encrypted document; requesting of the unconfirmed user to login to a second user account on the cloud computing network; authenticating the identity of the unconfirmed user as the second user; upon authenticating the identity of the unconfirmed user as the second user, decrypting the encrypted document to generate a decrypted document; storing the decrypted document in the first user account; granting the second user access to the decrypted file simultaneously to access granted to the first user; subsequent to the first user or the second user editing the decrypted document, encrypting an edited version of the decrypted document; and storing the edited version of the encrypted document in the first user account.
