🔐 macOS OpenSSH Patcher for Hardware Security Keys

Supports ED25519-SK with Yubikey and other FIDO2 hardware security keys!

🤔 Discussion

Despite being compiled to support hardware security keys that take advantage of the FIDO2 protocol, the built-in OpenSSH client on macOS Sonoma and above lacks the middleware/library to support these devices. To keep using the built-in client - which is often the most stable and secure method for SSH connections - we need to compile the Security Key Provider from OpenSSH source and tell the macOS client about it ourselves.

This script does all of that for you on both Apple Silicon and Intel Mac computers!

The script installs openssl and libfido2 along with the required build tools from Homebrew. It then clones the latest main branch of OpenSSH Portable and builds from it the Security Key Provider library: sk-libfido2.dylib. It finally moves the built library to /usr/local/lib/, modifies ~/.zshenv to expor

An Incomplete Taxonomy of Cross-Chain Messages

Single or Batched

Single Messages - Single messages have a single target address, target chainId, and data payload. The vast majority of cross-chain messages today are single messages.

Example:

function dispatchMessage(uint256 toChainId, address to, bytes calldata data) external payable returns (bytes32 messageId);
