.TH BITCOIN.CONF "5" "January 2011" "bitcoin.conf 3.19"
bitcoin.conf \- bitcoin configuration file
All command-line options (except for '\-conf') may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.
The configuration file is a list of 'setting=value' pairs, one per line, with optional comments starting with the '#' character.
The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, bitcoind(1) will look for a file named bitcoin.conf(5) in the bitcoin data directory, but both the data directory and the configuration file path may be changed using the '\-datadir' and '\-conf' command-line arguments.
bitcoin.conf should be located in $HOME/.bitcoin
Enable or disable run on the test network instead of the real *bitcoin* network.

Listen for RPC connections on this TCP port.
You can use *bitcoin* or *bitcoind(1)* to send commands to *bitcoin*/*bitcoind(1)* running on another host using this option.
Use Secure Sockets Layer (also known as TLS or HTTPS) to communicate with *bitcoin* '\-server' or *bitcoind(1)*. Example of OpenSSL settings used when *rpcssl*='1':
Acceptable ciphers (default: TLSv1+HIGH:\:!SSLv2:\:!aNULL:\:!eNULL:\:!AH:\:!3DES:\:@STRENGTH)
Enable or disable attempt to generate bitcoins.
Enable or disable use SSE instructions to try to generate bitcoins faster.
Pre-generate this many public/private key pairs, so wallet backups will be valid for both prior transactions and several dozen future transactions.

Allow direct connections for the 'pay via IP address' feature.
Enable or disable start bitcoind minimized.
