+//! Types for committing details of a connection.
+//!
+//! ## Commitment
+//!
+//! During the TLS handshake the Notary receives the Server's ephemeral public
+//! key, and this key serves as a binding commitment to the identity of the
+//! Server. The ephemeral key itself does not reveal the Server's identity, but
+//! it is bound to it via a signature created using the Server's
+//! X.509 certificate.
+//!
+//! A Prover can withhold the Server's signature and certificate chain from the
+//! Notary to improve privacy and censorship resistance.
+//!
+//! ## Proving the Server's identity
+//!
+//! A Prover can prove the Server's identity to a Verifier by sending a
+//! [`ServerIdentityProof`]. This proof contains all the information required to
+//! establish the link between the TLS connection and the Server's X.509
+//! certificate. A Verifier checks the Server's certificate against their own
+//! trust anchors, the same way a typical TLS client would.

-//! Attestation types.
+//! TLSNotary attestation types.
+//!
+//! # Introduction
+//!
+//! This library provides core functionality for TLSNotary **attestations**.
+//!
+//! Once the TLS commitment protocol has been completed the Prover holds a
+//! collection of commitments pertaining to the TLS connection. Most
+//! importantly, the Prover is committed to the
+//! [`ServerName`](tlsn_core::connection::ServerName),
+//! and the [`Transcript`](tlsn_core::transcript::Transcript) of application
+//! data. Subsequently, the Prover can request an [`Attestation`] from the
+//! Notary who will include the commitments as well as any additional
+//! information which may be useful to an attestation Verifier.
+//!
+//! Holding an attestation, the Prover can construct a
+//! [`Presentation`](crate::presentation::Presentation) which facilitates
+//! selectively disclosing various aspects of the TLS connection to a Verifier.
+//! If the Verifier trusts the Notary, or more specifically the verifying key of
+//! the attestation, then the Verifier can trust the authenticity of the
+//! information disclosed in the presentation.
+//!
+//! **Be sure to check out the various submodules for more information.**
+//!

 //! their own extensions.
+//!
+//! # Committing to the transcript
+//!
+//! The TLS commitment protocol produces commitments to the entire transcript of
+//! application data. However, we may want to disclose only a subset of the data
+//! in a presentation. Prior to attestation, the Prover has the opportunity to
+//! slice and dice the commitments into smaller sections which can be
+//! selectively disclosed. Additionally, the Prover may want to use different
+//! commitment schemes depending on the context they expect to disclose.
+//!
+//! The primary API for this process is the
+//! [`TranscriptCommitConfigBuilder`](tlsn_core::transcript::TranscriptCommitConfigBuilder)
+//! which is used to build up a configuration.
+//!
+//! ```no_run
+//! # use tlsn_core::transcript::{TranscriptCommitConfigBuilder, Transcript, Direction};
+//! # use tlsn_core::hash::HashAlgId;
+//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
+//! # let transcript: Transcript = unimplemented!();
+//! let (sent_len, recv_len) = transcript.len();
+//!
+//! // Create a new configuration builder.
+//! let mut builder = TranscriptCommitConfigBuilder::new(&transcript);
+//!
+//! // Specify all the transcript commitments we want to make.
+//! builder
+//!     // Use BLAKE3 for encoding commitments.
+//!     .encoding_hash_alg(HashAlgId::BLAKE3)
+//!     // Commit to all sent data.
+//!     .commit_sent(&(0..sent_len))?
+//!     // Commit to the first 10 bytes of sent data.
+//!     .commit_sent(&(0..10))?
+//!     // Skip some bytes so it can be omitted in the presentation.
+//!     .commit_sent(&(20..sent_len))?
+//!     // Commit to all received data.
+//!     .commit_recv(&(0..recv_len))?;
+//!
+//! let config = builder.build()?;
+//! # Ok(())
+//! # }
+//! ```
+//!
+//! # Requesting an attestation
+//!
+//! The first step in the attestation protocol is for the Prover to make a
+//! [`Request`](crate::request::Request), which can be configured using the
+//! associated [builder](crate::request::RequestConfigBuilder). With it the
+//! Prover can configure some of the details of the attestation, such as which
+//! cryptographic algorithms are used (if the Notary supports them).
+//!
+//! The Prover may also request for extensions to be added to the attestation,
+//! see [here](#extensions) for more information.
+//!
+//! Upon being issued an attestation, the Prover will also hold a corresponding
+//! [`Secrets`] which contains all private information. This pair can be stored
+//! and used later to construct a
+//! [`Presentation`](crate::presentation::Presentation), [see
+//! below](#constructing-a-presentation).
+//!
+//! # Issuing an attestation
+//!
+//! Upon receiving a request, the Notary can issue an [`Attestation`] which can
+//! be configured using the associated
+//! [builder](crate::AttestationConfigBuilder).
+//!
+//! The Notary's [`CryptoProvider`] must be configured with an appropriate
+//! signing key for attestations. See
+//! [`SignerProvider`](crate::signing::SignerProvider) for more information.
+//!
+//! # Constructing a presentation
+//!
+//! A Prover can use an [`Attestation`] and the corresponding [`Secrets`] to
+//! construct a verifiable [`Presentation`](crate::presentation::Presentation).
+//!
+//! ```no_run
+//! # use tlsn_attestation::{Attestation, CryptoProvider, Secrets, presentation::Presentation};
+//! # use tlsn_core::transcript::{TranscriptCommitmentKind, Direction};
+//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
+//! # let attestation: Attestation = unimplemented!();
+//! # let secrets: Secrets = unimplemented!();
+//! # let crypto_provider: CryptoProvider = unimplemented!();
+//! let (_sent_len, recv_len) = secrets.transcript().len();
+//!
+//! // First, we decide which application data we would like to disclose.
+//! let mut builder = secrets.transcript_proof_builder();
+//!
+//! builder
+//!     // Use transcript encoding commitments.
+//!     .commitment_kinds(&[TranscriptCommitmentKind::Encoding])
+//!     // Disclose the first 10 bytes of the sent data.
+//!     .reveal(&(0..10), Direction::Sent)?
+//!     // Disclose all of the received data.
+//!     .reveal(&(0..recv_len), Direction::Received)?;
+//!
+//! let transcript_proof = builder.build()?;
+//!
+//! // Most cases we will also disclose the server identity.
+//! let identity_proof = secrets.identity_proof();
+//!
+//! // Now we can construct the presentation.
+//! let mut builder = attestation.presentation_builder(&crypto_provider);
+//!
+//! builder
+//!     .identity_proof(identity_proof)
+//!     .transcript_proof(transcript_proof);
+//!
+//! // Finally, we build the presentation. Send it to a verifier!
+//! let presentation: Presentation = builder.build()?;
+//! # Ok(())
+//! # }
+//! ```
+//!
+//! # Verifying a presentation
+//!
+//! Verifying a presentation is as simple as checking the verifier trusts the
+//! verifying key then calling
+//! [`Presentation::verify`](crate::presentation::Presentation::verify).
+//!
+//! ```no_run
+//! # use tlsn_attestation::{CryptoProvider, presentation::{Presentation, PresentationOutput}, signing::VerifyingKey};
+//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
+//! # let presentation: Presentation = unimplemented!();
+//! # let trusted_key: VerifyingKey = unimplemented!();
+//! # let crypto_provider: CryptoProvider = unimplemented!();
+//! // Assert that we trust the verifying key.
+//! assert_eq!(presentation.verifying_key(), &trusted_key);
+//!
+//! let PresentationOutput {
+//!     attestation,
+//!     server_name,
+//!     connection_info,
+//!     transcript,
+//!     ..
+//! } = presentation.verify(&crypto_provider)?;

-# TLSNotary bench utilities
-
-This crate provides utilities for benchmarking protocol performance under various network conditions and usage patterns.
-
-As the protocol is mostly IO bound, it's important to track how it performs in low bandwidth and/or high latency environments. To do this we set up temporary network namespaces and add virtual ethernet interfaces which we can control using the linux `tc` (Traffic Control) utility.
-
-## Configuration
-
-See the `bench.toml` file for benchmark configurations.
-
-## Preliminaries
-
-To run the benchmarks you will need `iproute2` installed, eg:
-```sh
-sudo apt-get install iproute2 -y
-```
-
-## Running benches
-
-Running the benches requires root privileges because they will set up virtual interfaces. The script is designed to fully clean up when the benches are done, but run them at your own risk.
-
-#### Native benches
-
-Make sure you're in the `crates/benches/` directory, build the binaries, and then run the script:
-
-```sh
-cd binary
-cargo build --release
-sudo ./bench.sh
-```
-
-#### Browser benches
-
-(Note, we recommend running browser benches inside a docker container (see docker.md) to avoid
-facing incompatibility issues observed in the latest versions of Chrome.)
-
-With a Chrome browser installed on your system, make sure you're in the `crates/benches/` 
-directory, build the wasm module, build the binaries, and then run the script:
-```sh
-cd browser/wasm
-wasm-pack build --release --target web
-cd ../../binary
-cargo build --release --features browser-bench
-sudo ./bench.sh
-```
-
-## Metrics
-
-After you run the benches you will see a `metrics.csv` file in the working directory. It will be owned by `root`, so you probably want to run
-
-```sh
-sudo chown $USER metrics.csv
-```

-//! ## Commitment
-//!
-//! During the TLS handshake the Notary receives the Server's ephemeral public
-//! key, and this key serves as a binding commitment to the identity of the
-//! Server. The ephemeral key itself does not reveal the Server's identity, but
-//! it is bound to it via a signature created using the Server's
-//! X.509 certificate.
-//!
-//! A Prover can withhold the Server's signature and certificate chain from the
-//! Notary to improve privacy and censorship resistance.
-//!
-//! ## Proving the Server's identity
-//!
-//! A Prover can prove the Server's identity to a Verifier by sending a
-//! [`ServerIdentityProof`]. This proof contains all the information required to
-//! establish the link between the TLS connection and the Server's X.509
-//! certificate. A Verifier checks the Server's certificate against their own
-//! trust anchors, the same way a typical TLS client would.
