Account/key management

Cryptographic keys are an essential component of a GoQuorum network. GoQuorum uses keys to create digital signatures which verify a sender’s identity and prevent message tampering. The Privacy Manager uses keys to encrypt private transaction data.

Both GoQuorum and the Privacy Manager use user-provided asymmetric key pairs. Each key pair consists of a public key and a private key. The public key can be shared freely, but the private key should never be shared.

  • GoQuorum derives the account address from the public key by taking the last 20 bytes of its keccak256 hash
  • The Privacy Manager uses the public key as an identifier for the target nodes of a private transaction (that is the privateFor transaction field)

Key management determines how GoQuorum and Tessera store and use private keys.

ConsenSys has acquired Quorum from J.P. Morgan. Please read the FAQ.
