BSV Message Encryption

Encrypt and decrypt messages between parties using @bsv/sdk.

Recommended: Use EncryptedMessage from @bsv/sdk

The @bsv/sdk provides EncryptedMessage for secure message encryption. This is the preferred approach - avoid rolling custom encryption implementations.

import { PrivateKey, EncryptedMessage, Utils } from '@bsv/sdk'

const sender = PrivateKey.fromRandom()
const recipient = PrivateKey.fromRandom()

// Encrypt: sender uses their private key + recipient's public key
const message = Utils.toArray('Secret message', 'utf8')
const encrypted = EncryptedMessage.encrypt(message, sender, recipient.toPublicKey())
