OK, thanks. I build off a local branch either way, with regular rebasing. Easier for me to replace the code :) Stijn ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

[OpenWrt-Devel] Sha256 checksum generation of images: why OpenSSL instead of sha256sum?

Hi guys, I have a nice script on my routers that pulls in a new firmware image, validates the checksum, then flashes it. I switched it to sha256 (from md5), noticed the format in the sha256sums was different, but didn't pay it too much mind - except that now, the busybox sha256sum function
