Examples
-
Public-Key Cryptography - Demonstrates how to generate a
random secret-key and corresponding public-key, sign some bytes using a
secret-key, validate the signature for some bytes using a public-key, encrypt
some bytes using a public-key, and how to decrypt a ciphertext using a
secret-key.
-
Threshold Encryption - Demonstrates how to encrypt a
message to a group of actors with a master public-key, where the number of
actors collaborating in the decryption process must exceed a given threshold
number before the ciphertext can be successfully decrypted. This example also
demonstrates the idea of a "trusted dealer", i.e. some trusted entity that is
responsible for generating the keys.
-
Threshold Signing - Demonstrates how threshold signing
can be used to generate an append-only ledger of chat messages. Each node
running our chat protocol receives and signs messages (using its share of the
network's master secret-key). The network adds a new message to the ledger once
enough nodes (threshold + 1) have signed a given message.
