spake2p tool provides command line interface (CLI) utility used for generating spake parameters (PIN code and verifier) for device manufacturing provisioning.
Specify ‘help’ option for the detailed ‘spake2p’ tool usage instructions:
./spake2p help
Specify ‘--help’ option for detail instructions on command usage:
./spake2p gen-verifier --help
Example command that generates spake2p verifier for a given PIN code:
./spake2p gen-verifier --pin-code 45502684 --iteration-count 1000 --salt "U1BBS0UyUCBLZXkgU2FsdA==" --out spake2p-provisioning-data.csv
Example command that generates 100 sets of spake2p parameters (random PIN Codes, random Salts and corresponding Verifiers):
./spake2p gen-verifier --count 100 --iteration-count 15000 --salt-len 32 --out spake2p-provisioning-data.csv
Example command that generates 100 sets of spake2p parameters (Specific PIN Codes, random Salts and corresponding Verifiers):
./spake2p gen-verifier --count 100 --pin-code-file pincodes.csv --iteration-count 15000 --salt-len 32 --out spake2p-provisioning-data.csv
Notes: Each line of the pincodes.csv should be a valid PIN code. You can use spake2p --help to get the example content of the file.
