• 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.
