How to share a key among devs
First split the key with ssss. We usually go with 2 required shares. Create excess shares so you can distribute some to potential new devs:
ssss-split -t 2 -n 8
(copy in the key)
The output is a list of keys like
1-jacriejuajrie
2-juajriecrie
...
Then send messages to each dev (replace DEV and SITE by the appropriate info):
Hi DEV, This is a share for the key of SITE
I split the password with Shamirs Secret Sharing Scheme: http://point-at-infinity.org/ssss/
Two shares are needed to recover the password if I should be hit by a bus.
Recombine them with ssss-combine -t 2
Your share is:
N-............
(the key is on its own line, so they can simply copy by triple-clicking)
