Reclaim crypto SDK
Crypto SDK Provides common functions for encrypting, decrypting, signing & verifying data used in Reclaim protocol. It's also used for generating & verifying auth tokens used in Reclaim backend
Setup
- Run
npm i
Creating an account
- Generate a new wallet by calling
const wallet = Wallet.createRandom()
Authentication
- Create an auth token by calling
await generateAuthToken(wallet.privateKey) - Validate token by calling
authenticate(token)
Encrypting & decrypting data
Encryption
const data = Buffer.from('{"a":"123","b":123}', 'utf8')
const ciphertext = encryptData(
utils.arrayify(bob.publicKey),
utils.arrayify(alice.privateKey),
data
)Decryption
const plaintext = decryptData(
utils.arrayify(bob.privateKey),
utils.arrayify(alice.publicKey),
ciphertext
)Signing & verification
const data = Buffer.from('{"a":"123","b":123}', 'utf8')
const signature = await signatures.sign(
data,
privateKey,
)Verification
const addr = signatures.getAddress(utils.arrayify(publicKey))
const res = await signatures.verify(data,signature,addr)
