Encryption
is primarily used to safeguard the contents of a message so that only
the intended recipient could read it. This is done by replacing the
contents with unrecognizable data, which could be understood only by the
intended recipient. This is how encryption became a method to protect
data from those who might want to steal it.
Encryption can be used in two situations.
- Encryption in Transit.
- Encryption at Rest (EAR).
Encryption in Transit
Refers
to data that is encrypted when it is in transit — including from your
browser to the web server and other third parties via
integrations.Encrypting data in transit protects your data from
man-in-the-middle-attacks. Learn more about Encryption in Transit.
Encryption at Rest
Refers
to data that is encrypted when it is stored (not moving) — either on a
disc, in a database, or some other form of media. Besides encryption of
data during transit, encryption of data when it is stored in the servers
provides an even higher level of security. EAR protects against any
possible data leak due to server compromise or unauthorized access. Encryption is done at the application layer using the AES-256
algorithm which is a symmetric encryption algorithm and uses 128-bit
blocks and 256-bit keys.The key used to convert the data from plain text
to cipher text is called Data Encryption Key(DEK). The DEK is further
encrypted using the KEK (Key Encryption Key), thus, providing yet
another layer of security.The keys are generated and maintained by our
in-house Key Management Service(KMS).Learn more about our KMS.

Full-disk Encryption
Besides
application layer encryption, full disk encryption is available in
India (IN), Australia (AU) and Japan (JP) datacenters.
