@raytio/core v11.3.0
@raytio/core
@raytio/core is a collection of low-level functions for using the Raytio API. It works in both the browser and a nodejs environment, although nodejs requires several polyfills (see below).
For a high-level and easy-to-use API, consider using @raytio/decrypt-helper.
Usage in nodejs
Nodejs does not support fetch, WebCrypto, or atob/btoa, so these will need to be polyfilled. Older versions of nodejs (<14.0.0) also do not support TextEncoder or Intl.DateTimeFormat.
If you use the high-level @raytio/decrypt-helper module, you don't need to worry about this.
If you wish to use @raytio/core directly, an example of configuring polyfills for nodejs is availble here

Returns
Promise<ScoreResult>
checkJsonSignature
▸ checkJsonSignature(data, signature, keyId): Promise<boolean>
checks that a json object was signed by the provided signature. Unless you're
dealing with bundled verifications, you should use getOwnRealVerifications
or getSomeoneElsesRealVerifications instead.
Parameters

data | unknown |
signature | string |
keyId | undefined | string |
Returns
Promise<boolean>
convertInstanceToRuleInput
▸ convertInstanceToRuleInput(POs, realVers, getSchema): Promise<RuleData>

Converts relationship type used by the server into the (Urn format) type used by the client
Parameters
| Name | Type | Description |
|---|---|---|
serverRelationship | ServerRelationship | relationship type used in the server |
Returns
Relationship
a Relationship (client-side type) that is equivalent to the inputted serverRelationship value
createAA
▸ createAA(«destructured»): Promise<AA>
Creates an Access Application and associated public+private keys.
The user must be part of an organization, and you need to include the orgId.
You must also supply an apiToken and an instance of the maxcryptor for that user,
as well as the userDoc data which is stored in the user's cognito attributes.
Parameters
| Name | Type |
|---|---|
«destructured» | Object |
› apiToken | string |
› apiUrl | string |
› application | Omit<AA, "a_id"> |
› maxcryptor | DataEncryptorI |
› userDoc | UserDoc |
Returns
Promise<AA>
createHashedNId
▸ createHashedNId(nId, aId): NId
the API returns hashed NIds in a separate field,
which breaks the whole app. So, we move the hashed ID into
the normal n_id field, and use a different format.
This was first introduced in #1048
Parameters
| Name | Type |
|---|---|
nId | NId |
aId | AId |
Returns
NId
decryptSharedData
▸ decryptSharedData(«destructured»): Promise<{ applicationDecryptor: ApplicationDataEncryptorI ; instance: Instance }>
Decrypts any encrypted properties included in the supplied instanceData.
If nothing is encrypted the supplied instanceData is returned.
It will reject if there are keys missing for any encrypted properties, or
if the encrypted data is invalid. If you don't want it to reject, you can
supply a onCorruptedData function which returns a value to use instead.
Parameters
| Name | Type |
|---|---|
«destructured» | Object |
› apiToken | string |
› apiUrl | string |
› instanceData | Instance |
› maxcryptor | DataEncryptorI |

Returns
Promise<{ applicationDecryptor: ApplicationDataEncryptorI ; instance: Instance }>
a copy of instanceData with all properties decrypted.
