Various bindings for us. Highly experimental.
The bindings accept contracts in the form of a 96-byte array, consisting of the
host public key, file contract ID, and renter secret key. The easiest way to
acquire such a contract is via user:
user form [host key] 100SC 1000 example.contract
xxd -ps -s 12 -l 96 example.contract | tr -d '\n'
This will print the contract as a 192-byte hex string. You can convert this to a QR code using a local program/library or any number of online generator services.
It is also possible to convert siad contracts to this format, but it's a
little trickier. I will provide a script to perform the conversion upon request.
