Utilizing encryption key exchange with access permissions to share passwords among devices via a shared folder

Abstract

This disclosure describes methods, non-transitory computer readable storage media, and systems that provide secure password sharing across a plurality of users and client devices via a shared folder. For example, in one or more embodiments, the disclosed system retrieves a public key set including public encryption keys for client devices having access to the shared folder. The disclosed system provides the public key set to a client device requesting to share the shared folder. The disclosed system receives an encrypted payload for the shared folder and a shared encryption key that is utilized to encrypt the payload and is encrypted in the shared folder utilizing the public key set. The disclosed system also detects key rotation events and notifies one or more client devices to generate a modified shared encryption key and re-encrypt the payload for storage within the shared folder.
