Abstract: Disclosed herein are methods, processor programs, and cryptography products for managing cryptographic keys. The methods, processor programs, and cryptography products disclosed herein can protect keys stored in a database against a wide variety of malicious attacks. The methods, processor programs, and products disclosed herein may include a variety of mechanisms that wrap a key in several layers of protection. According to one exemplary embodiment disclosed herein, a method of managing cryptographic keys includes accessing at a server a server key, accessing at the server a client key, accessing at the server an encrypted private key provided by a client, encrypting the encrypted private key with the server key to generate a twice encrypted private key, and encrypting the twice encrypted private key with the client key to generate a thrice encrypted private key.

Abstract: The disclosure describes a method of communication over a network. The method includes receiving at a server an HTTP (HyperText Transfer Protocol) request from a client over a network connection. After receiving notification of an event asynchronous to the receipt of the HTTP request, the server sends an HTTP response to the client identifying the asynchronous event.
