Encryprion, 1st paragraph |
There are two types of encryption: symmetric and asymmetric. Symmetric encryp‐
tion encodes data with a key, so only those who know that key can decipher the data.
In asymmetric encryption, there are two keys, one for encryption (public key) and
the other for decryption (private key). The sender encrypts data using the receiver’s
public key, and the receiver deciphers data using their private key. Presto uses asym‐
metric encryption. In any distributed environment, including a Presto cluster, you
can implement two types of encryption: encryption over the wire and encryption at
REST:
1. Presto uses not asymmetric, but symmetric encryption. TLS, TDE in Oracle and Parquet Encryption (prestodb.io / blog / 2022 / 07 / 10 / presto-parquet-column-encryption /) use different kinds of symmetric algorithms.
2. Rest means "quiescency", it's not the acronym. REST as «representative state transfer» is about API, not about encryption.
