Revision b08edf709dfcd79c3691370930cd89c4b9b16d2f authored by Jeff King on 01 February 2023, 11:39:26 UTC, committed by Junio C Hamano on 01 February 2023, 18:10:34 UTC
Recent versions of openssl will refuse to work with 1024-bit RSA keys, as they are considered insecure. I didn't track down the exact version in which the defaults were tightened, but the Debian-package openssl 3.0 on my system yields: $ LIB_HTTPD_SSL=1 ./t5551-http-fetch-smart.sh -v -i [...] SSL Library Error: error:0A00018F:SSL routines::ee key too small 1..0 # SKIP web server setup failed This could probably be overcome with configuration, but that's likely to be a headache (especially if it requires touching /etc/openssl). Let's just pick a key size that's less outrageously out of date. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
