What is End-To-End Ecryption
encryption keys must only be known to the communicating parties. E2EE systems can encrypt data using a pre-arranged string of symbols, called a pre-shared secret (PGP, Pretty Good Privacy), or a one-time secret derived from such a pre-shared secret (DUKPT, Derived Unique Key Per Transaction). They can also negotiate a secret key on the spot using Diffie-Hellman key exchange (OTR).

What is TDE
Transparent Data Encryption - encrypts the data within the physical files of the database, the 'data at rest'. Without the original encryption certificate and master key, the data cannot be read when the drive is accessed or the physical media is stolen
