[PATCH v2 25/35] remote-curl: make hash size independent

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Feb 19, 2019, 00:05 UTC
Message-ID
<20190219000526.476553-26-sandals@crustytoothpaste.net>
In-Reply-To
<20190219000526.476553-1-sandals@crustytoothpaste.net>

Change one hard-coded use of the constant 40 to a reference to the_hash_algo. In addition, switch a use of get_oid_hex to parse_oid_hex to avoid the need to use a constant.
