Secure chat

Real-time messaging concentrates data that can be very sensitive, so it must meet strict security and privacy requirements.

End-to-end encryption of messages, files, etc. exchanged ensures their security by design since they will only be decryptable by authorized users, you yourself will not be able to decrypt them.

Finally, Seald handles encryption for multiple devices and for groups so you can focus on the rest.

Quickly integrate encryption into your applications with Seald SDKs. You don't need skills in cryptography to integrate them.

import SealdSDK from '@seald-io/sdk'

// Initialize the SDK
const seald = SealdSDK({ apiURL, appId })
// Create your Seald identity
await seald.initiateIdentity({ signupJWT })
// Encrypt a message for another user
const encryptedMessage = await seald.encryptMessage(
  'Super secret message',
   { userIds: ['BOB_002'] }
)

// And *voilà*!
const message = await seald.decryptMessage(encryptedMessage)
