Description
===========

**taler-exchange-keyup** is a command line tool to setup Taler
denomination and signing keys. This tool requires access to the
exchange’s long-term offline signing key and should be run in a secure
(offline) environment under strict controls. The resulting keys can then
be copied to the main online directory where the Taler HTTP server
operates.

Its options are as follows:

**-d** *DIRNAME* \| **–exchange-dir=**\ ‌\ *DIRNAME*
   Use the configuration and other resources for the exchange to operate
   from *DIRNAME*.

**-h** \| **–help**
   Print short help on options.

**-m** *FILE* \| **–master-key=**\ ‌\ *FILE*
   Location of the private EdDSA offline master key of the exchange.

**-o** *FILE* \| **–output=**\ ‌\ *FILE*
   Where to write a denomination key signing request file to be given to
   the auditor.

**-r** *DKH* \| **–revoke=**\ ‌\ *DKH*
   Revoke the denomination key where the denomination public key’s hash
   is DKH.

**-t** *TIMESTAMP* \| **–time=**\ ‌\ *TIMESTAMP*
   Operate as if the current time was *TIMESTAMP*.

**-v** \| **–version**
   Print version information.
