thingy-crypto-node
Background
Thingy Nodes usually have an assymetric keypair - this way all authentication works between the nodes in the thingy-ecosystem. The thingy-crypto-node is the keeper of the keypair of this node - implementing all basic crypto functionality for this specific keypair.
Usage
Current Functionality
import { ThingyCryptoNode } from "thingy-crypto-node"
options = {
secretKeyHex: "..." # required
publicKeyHex: "..." # required
context: "..." # optional
}
cryptoNode = new ThingyCryptoNode(options)
## Signing and Verifiying
content = STRING
signatureHex = await cryptoNode.sign(content)
signatureHex = STRINGHEX
true = await cryptoNode.verify(signatureHex, content)
## Encrypting and Decrypting
content = STRING
secretsObject = await cryptoNode.encrypt(content)
secretsObject = { referencePointHex, encryptedContentHex }
secretsObject = { STRINGHEX, STRINGHEX }
content = await cryptoNode.decrypt(secretsObject)
## DiffieHellman For shared secret with specific foreign node
id = STRINGHEX64
salt = STRING
timestamp = NUMBER
sharedSecretHex = await cryptoNode.diffieHellmanFor(id, salt, timestamp)
sharedSecretHex = STRINGHEX128
Further steps
- Add more features when the requirement pops up.
