Bitwarden uses zero-knowledge encryption, meaning the company can't see its users' data. This is achieved by end-to-end encrypting vault data with AES-CBC 256-bit and by using PBKDF2 SHA-256/Argon2id to derive the encryption key. [9] [10]
The term "end-to-end encryption" originally only meant that the communication is never decrypted during its transport from the sender to the receiver. [9] For example, around 2003, E2EE has been proposed as an additional layer of encryption for GSM [10] or TETRA, [11] in addition to the existing radio encryption protecting the communication between the mobile device and the network infrastructure.
The symmetric encryption key is maintained independently from the computer's CPU, thus allowing the complete data store to be encrypted and removing computer memory as a potential attack vector. Hardware-FDE has two major components: the hardware encryptor and the data store. There are currently four varieties of hardware-FDE in common use:
This key is itself encrypted in some way using a password or pass-phrase known (ideally) only to the user. Thereafter, in order to access the disk's data, the user must supply the password to make the key available to the software. This must be done sometime after each operating system start-up before the encrypted data can be used.
Diagram showing the possible points of encryption within a storage network. The encryption of data can take place in many points in a storage network. The point of encryption may occur on the host computer, in the SAN infrastructure, the array controller or on each of the hard disks as shown on the diagram above.
Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table. Partition: Whether individual disk partitions can be encrypted. File: Whether the encrypted container can be stored in a file (usually implemented as encrypted loop devices).
Client-side encryption is the cryptographic technique of encrypting data on the sender's side, before it is transmitted to a server such as a cloud storage service. [1] Client-side encryption features an encryption key that is not available to the service provider, making it difficult or impossible for service providers to decrypt hosted data.
