3//! ## Oblivious Transfer protocols
4//!
5//! 1. [Simplest OT protocol](./src/base_ot/simplest_ot.rs)
6//! 2. [Naor Pinkas OT](./src/base_ot/naor_pinkas_ot.rs)
7//! 3. [Endemic OT](./src/base_ot/endemic_ot.rs)
8//!
9//! ## Oblivious Transfer Extensions
10//! 1. [ALSZ](./src/ot_extensions/alsz_ote.rs)
11//! 2. [KOS](./src/ot_extensions/kos_ote.rs)
12//!
13//! ## Oblivious Transfer based multiplication
14//! 1. [DKLS18](./src/ot_based_multiplication/dkls18_mul_2p.rs) - 2 party multiplication of where each party has a single input
15//! 2. [DKLS19](./src/ot_based_multiplication/dkls19_batch_mul_2p.rs) - 2 party batch-multiplication of where each party has multiple inputs, say `n` inputs and those inputs will be multiplied, i.e. a total of `2*n` multiplications will be done with each being between 2 inputs
