keosd is a key manager service daemon for storing private keys and signing digital messages. It provides a secure key storage medium for keys to be encrypted at rest in the associated wallet file. keosd also defines a secure enclave for signing transaction created by cleos or a third part library.


keosd is distributed as part of the EOSIO software suite. To install keosd just visit the EOSIO Software Installation section.


When a wallet is unlocked with the corresponding password, cleos can request keosd to sign a transaction with the appropriate private keys. Also, keosd provides support for hardware-based wallets such as Secure Encalve and YubiHSM.


keosd is intended to be used by EOSIO developers only.
