@ohos.security.huks (HUKS)

The HUKS module provides KeyStore (KS) capabilities for applications, including key management and key cryptography operations. The keys managed by OpenHarmony Universal KeyStore (HUKS) can be imported by applications or generated by calling the HUKS APIs.

NOTE

The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Modules to Import

import huks from '@ohos.security.huks'

HuksParam

Defines the param in the properties array of options used in the APIs.

System capability: SystemCapability.Security.Huks.Core

Name Type Mandatory Description
tag HuksTag Yes Tag.
value boolean|number|bigint|Uint8Array Yes Value of the tag.

HuksOptions

Defines the options used in the APIs.

System capability: SystemCapability.Security.Huks.Core

Name Type Mandatory Description
properties Array<HuksParam> No Properties used to hold the HuksParam array.
inData Uint8Array No Input data.

HuksSessionHandle9+

Defines the HUKS handle structure.

System capability: SystemCapability.Security.Huks.Core

Name Type Mandatory Description
handle number Yes Value of the handle.
challenge Uint8Array No Challenge obtained after the initSession operation.

HuksReturnResult9+

Defines the HuksResult struct.

System capability: SystemCapability.Security.Huks.Core

Name Type Mandatory Description
outData Uint8Array No Output data.
properties Array<HuksParam> No Property information.
certChains Array<string> No Certificate chain information.

huks.generateKeyItem9+

generateKeyItem(keyAlias: string, options: HuksOptions, callback: AsyncCallback<void>) : void

Generates a key. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Security.Huks.Core

Parameters

Name Type Mandatory Description
keyAlias string Yes Alias of the key.
options HuksOptions Yes Tags required for generating the key. The algorithm, key purpose, and key length are mandatory.
callback AsyncCallback<void> Yes Callback invoked to return the result. If no error is captured, the key is successfully generated. In this case, the API does not return the key content because the key is always protected in a TEE. If an error is captured, an exception occurs in the generation process.

Error codes

For details about the error codes, see HUKS Error Codes.

/* Generate an ECC key of 256 bits. */
class HuksProperties {
    tag: huks.HuksTag = huks.HuksTag.HUKS_TAG_ALGORITHM

    });
} catch (error) {
    console.error(`callback: generateKeyItem input arg invalid`);
}

huks.generateKeyItem9+

generateKeyItem(keyAlias: string, options: HuksOptions) : Promise<void>

Generates a key. This API uses a promise to return the result. Because the key is always protected in a trusted environment (such as a TEE), the promise does not return the key content. It returns only the information indicating whether the API is successfully called.

System capability: SystemCapability.Security.Huks.Extension

Parameters

Name Type Mandatory Description
keyAlias string Yes Alias of the key.
options HuksOptions Yes Tags required for generating the key. The algorithm, key purpose, and key length are mandatory.

attestKeyItem(keyAlias: string, options: HuksOptions) : Promise<HuksReturnResult>

Obtains the certificate used to verify a key. This API uses a promise to return the result.

System capability: SystemCapability.Security.Huks.Extension

Parameters

Name Type Mandatory Description
keyAlias string Yes Alias of the key. The certificate to be obtained stores the key.
options HuksOptions Yes Parameters and data required for obtaining the certificate.

Return value

Type Description
Promise<HuksReturnResult> Promise used to return the result. If the operation is successful, no err value is returned; otherwise, an error code is returned.
