This allowed users to create invalid Ed25519 Extended Secret Keys with potentially cryptographically weak ECDSA Signatures. However we still allow to have an _unsafe_ version to construct a `SecretKeyExtended` from bytes without performing checks. This is in order to allow a compatibility path without breaking codes too much. allow the direct conversion from XPrv from ed25519_bip32 crates to pallas-crypto's SecretKeyExtended without performing the bit tweaks check While it is unsafe to call the SecretKeyExtended::from_bytes_unchecked (unsafe in the cryptographic sense, not in the rust memory management sense) we know this is going to be okay because the XPrv was already safely created. We previously removed the direct conversion of byte arrays into SecretKeyExtended This has been replaced with a `TryFrom` and a `from_bytes() -> Result<Self>` function. This allows us to perform the recovery of the wrapped private keys without losing the security of performing the checks of the validity of the Ed25519 Extended structure. This should be safe to use and shouldn't make incompatibilities because the Xprv was already checked for bit tweaks previously in the flow. add unsafe functions to leak the content of the SecretKey or SecretKeyExtended Remove the From implementation to convert Secret Keys into Bytes Instead prefer the explicit unsafe functions to leak the content of the keys temporarily remove the public access of the as_bytes function this is to prevent leaking the bytes of the private keys. |

Rust-native building blocks for the Cardano blockchain ecosystem
Introduction
Pallas is an expanding collection of modules that re-implements common Ouroboros / Cardano logic in native Rust. This crate doesn't provide any particular application, it is meant to be used as a base layer to facilitate the development of higher-level use-cases, such as explorers, wallets, etc (who knows, maybe even a full node in a far away future).
Unboxing
The repository is organized as a Cargo workspace. Each Pallas "building block" lives in its own crate. The root pallas crate serves as an all-in-one dependency that re-exports all of the other modules in an hierarchically organized fashion, using Cargo features to tailor the setup for each use-case.
As already explained, Pallas aims at being an expanding set of components. The following tables describe the currently available crates, as well as the planned ones.
Ouroboros Network
| Crates | Description |
|---|---|
| pallas-network | Network stack providing a multiplexer and mini-protocol implementations |
Ouroboros Consensus
| Crates | Description |
|---|---|
| pallas-leadership | Implementation of the slot leadership selection algorithm |
| pallas-selection | Implementation of the consensus chain-selection algorithm |
Cardano Ledger
| Crates | Description |
|---|---|
| pallas-primitives | Ledger primitives and cbor codec for the different Cardano eras |
| pallas-traverse | Utilities to traverse over multi-era block data |
| pallas-addresses | Encode / decode Cardano addresses of any type |
| pallas-ticking | Time passage implementation for consensus algorithm |
| pallas-applying | Logic for validating and applying new blocks and txs to the chain state |
| pallas-forecasting | Ledger forecasting algorithm to be used by the consensus layer |
Shared
| Crates | Description |
|---|---|
| pallas-crypto | Shared Cryptographic primitives |
| pallas-codec | Shared CBOR encoding / decoding using minicbor lib |
