Abstract
Methods, systems and computer readable mediums are provided for recovering keys. A key transport session key is generated, and a key encryption key is derived based on a server master key and an identification associated with a token. The key transport session key is encrypted with the key encryption key as a first wrapped key transport session key. An encrypted storage session key and an encrypted private key are retrieved from an archive. The encrypted storage session key is decrypted with a server storage key as a storage session key. The encrypted private key is decrypted with the storage session key. The decrypted private key is encrypted with the key transport session key as a wrapped private key. The wrapped private key and the first wrapped key transport session key are forwarded.
