@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.

Example

import huks from '@ohos.security.huks';
/* Generate an ECC key of 256 bits. */
class HuksProperties {
    tag: huks.HuksTag = huks.HuksTag.HUKS_TAG_ALGORITHM
    value: huks.HuksKeyAlg|huks.HuksKeySize|huks.HuksKeyPurpose|huks.HuksKeyDigest = huks.HuksKeyAlg.HUKS_ALG_ECC

    {
        tag: huks.HuksTag.HUKS_TAG_KEY_SIZE,
        value: huks.HuksKeySize.HUKS_ECC_KEY_SIZE_256
    },
    {

        }
    });
} 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.
