Abstract
Disclosed embodiments relate to securely caching and provisioning secrets for use in an offline process. Techniques include accessing, at an endpoint computing resource storing a secret, a first cryptographic key; encrypting the secret using the first cryptographic key; receiving, from an auxiliary device, a second cryptographic key; encrypting the encrypted secret with the second cryptographic key to produce an encrypted block; sending, without using a network connection, the encrypted block to the auxiliary device for decryption; receiving, from the auxiliary device and without using a network connection, a decrypted version of the encrypted block; and decrypting the encrypted secret with a cryptographic key corresponding to the first cryptographic key.
