Encryption in Zoho Solo
Encryption is primarily used to safeguard the contents of a message so that only the intended recipient can read it. This is done by replacing the contents with unrecognizable data, which can be understood only by the intended recipient. This is how encryption became a method to protect data from those who may want to steal it.
Encryption can be used in two situations:
- Encryption in Transit
- Encryption at Rest (EAR)
Encryption in Transit
This 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.
Encryption at Rest
This 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. In addition to 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 two layers of security: the Data Encryption Key (DEK) and the KEK (Key Encryption Key). These keys are generated and maintained by our in-house Key Management Service(KMS). You can learn more about EAR here.
