Crate steel_crypto 

Cryptographic utilities for SteelMC, focused on RSA signing and verification for secure chat message validation.

This module implements the cryptographic primitives needed for Minecraft’s signed chat system, including RSA key pair generation, SHA256withRSA signing, and signature verification.

Modules

key_store

This module contains the KeyStore struct, which is used to store the server’s encryption keys.

rsa_utils

RSA key pair generation and encoding utilities.

signature

RSA signature creation and verification utilities.

Constants

RSA_KEY_BITS

Size of RSA keys in bits

SIGNATURE_BYTES

Size of RSA signatures in bytes (for 1024-bit RSA keys, signatures are 128 bytes) Note: Minecraft protocol specifies 256 bytes, but 1024-bit RSA produces 128-byte signatures

SIGNING_ALGORITHM

Signing algorithm used for chat messages (SHA256withRSA)
