loading caibx header failed

[devhigh29]

While trying to extract, i am getting the following error

sudo csn /tmp/foo.caibx /dev/mmcblk1p6 http://192.168.0.93:8080/default.castr/
caibx.c:load_index_header:65 unsupported feature set: 0xa000000000000000
main.c:csn:124 loading caibx header failed
main.c:main:270 initializing synchronization process failed

The same caibx file is working with casync, i only see this error with casync-nano

The feature flag set displayed in the error message means that you're trying to extract a caibx file that uses SHA512/256 hashes. casync-nano only supports SHA256 because on the class of devices it is meant for (roughly 32bit ARM processors), SHA512 is significantly slower than SHA256. You can get casync make to generate compatible indices by using --digest=sha256. Note that while this will result in the same chunks as in the default settings, but they will have different IDs because of the different hash algorithm.

Thanks, it solved the issue.
