TLS communication

Web3Signer supports TLS to secure inbound and outbound HTTP JSON-RPC requests, and communication with HashiCorp Vault.

Private keys and certificates for client and server TLS connections must be stored in password-protected PKCS #12 keystores. The server (in this example, Hyperledger Besu) must be configured to accept TLS connections.

Use the command line options to configure TLS on HTTP JSON-RPC requests and HashiCorp Vault.
