PEP is an acronym for "Polymorphic Encryption and Pseudonymization", which hints at its [features](#features) and at the technology on which it is based.
PEP is an acronym for "Polymorphic Encryption and Pseudonymization". Functionally, PEP is software for the storage and retrieval of tabular data. PEP's storage consists of a single table. This rather limited [data structure](Data-structure) is offset by some features that run-of-the-mill database systems do not normally provide:
Functionally, PEP is software for the storage and retrieval of tabular data. PEP's storage consists of a single table. This rather limited [data structure](Data-structure) is offset by some features that run-of-the-mill database systems do not normally provide:
- PEP [encrypts](#encryption) data both [at rest](https://en.wikipedia.org/wiki/Data_at_rest#Encryption) and in transit, effectively providing [end-to-end encryption](https://en.wikipedia.org/wiki/End-to-end_encryption) between the data's uploader(s) and downloader(s).

- PEP [ensures](#trust-reduction) that no single server or administrator or hosting party can access the data (or provide access to it) by themselves.
