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

1. Run npm i

Creating an account

1. Generate a new wallet by calling const wallet = Wallet.createRandom()

Authentication

1. Create an auth token by calling await generateAuthToken(wallet.privateKey)
2. Validate token by calling authenticate(token)

Encrypting & decrypting data

$3

``typescript
const data = Buffer.from('{"a":"123","b":123}', 'utf8')
const ciphertext = encryptData(
utils.arrayify(bob.publicKey),
utils.arrayify(alice.privateKey),
data
)
`

$3

`typescript
const plaintext = decryptData(
utils.arrayify(bob.privateKey),
utils.arrayify(alice.publicKey),
ciphertext
)
`

Signing & verification

`typescript
const data = Buffer.from('{"a":"123","b":123}', 'utf8')
const signature = await signatures.sign(
data,
privateKey,
)
`

$3

`typescript
const addr = signatures.getAddress(utils.arrayify(publicKey))
const res = await signatures.verify(data,signature,addr)
