deadserious Report post Posted August 19, 2013 I am creating my own shared secrets and would like to calculate what the read-only secret would be for that ID without entering it into the GUI. I assumed it was a hash-base64 encode of the writable shared secret, but can't find the right hash, so probably am way off.Can someone toss me a bone and share how the readonly key is calculated from the shared secret?

Disappointed Cat Report post Posted August 19, 2013 The devs are over secretive to disclose internals as yet - but there is a way to generate RO keys from RW keys:btsync --get-ro-secret <full-access-secret>The process is different for standard secrets and custom/longer secrets so this is the best way to do it anyway.

When I try I just get an error that BTSync is already running. Quote Share this post Link to post Share on other sites

deadserious Report post Posted August 20, 2013 Indeed. Try the linux binary under cygwin just for this or use a linux instance remotely. Unfortunately the first isn't feasible for my usecase. The second might work as a temporary hack I guess. But that won't be workable long term for what I'm building. Quote Share this post Link to post Share on other sites

deadserious Report post Posted August 20, 2013 Can someone toss me a bone and share how the readonly key is calculated from the shared secret?So far it appears that the Read only secret is the string "RONLY" followed by a 512 bit hash of something then urlencoded.I'm having a hard time figuring out what that 512 bit hash is. I've tried hashing the original secret with SHA2 and SHA3. It might be multiple iterations, but so far I haven't figured out how many if it is. If anyone else has any input or findings, that would be great. Quote Share this post Link to post Share on other sites
deadserious Report post Posted August 21, 2013 It would be great if I could get an official response from the Sync team. Even if they aren't permitted to give out this info yet, I'd like to hear that they know about this request for help. Quote Share this post Link to post Share on other sites
