+# HUKS Changelog
+
+## cl.huks.1 HUKS Supports RsaPssSaltLengthType
+
+Before the change, the HUKS uses **RSA_PSS_SALT_LEN_MAX** for signing or signature verification by default.
+
+After the change, the type defined by **HuksRsaPssSaltLenType** is passed in for signature or signature verification. If **HuksRsaPssSaltLenType** is not passed in, **RSA_PSS_SALT_LEN_MAX** is used by default.
+
+**Change Impact**
+
+Behaviors of released JavaScript APIs have been changed.
+
+**Key API/Component Changes**
+
+Released JavaScript APIs remain unchanged, but the parameter set passed to the APIs are changed.
+
+**Adaptation Guide**
+
+The following uses RSA signing as an example.
+
+```js
+import huks from '@ohos.security.huks';
+
+let keyAlias = 'rsa_Key';
+let inData = new Uint8Array(
+    0x4B, 0x1E, 0x22, 0x64, 0xA9, 0x89, 0x60, 0x1D, 0xEC, 0x78, 0xC0, 0x5D, 0xBE, 0x46, 0xAD, 0xCF,
+    0x1C, 0x35, 0x16, 0x11, 0x34, 0x01, 0x4E, 0x9B, 0x7C, 0x00, 0x66, 0x0E, 0xCA, 0x09, 0xC0, 0xF3,
+);
+/* Parameters for signing */
+let signProperties = new Array();
+signProperties[0] = {
+    tag: huks.HuksTag.HUKS_TAG_ALGORITHM,
+    value: huks.HuksKeyAlg.HUKS_ALG_RSA,
+}
+signProperties[1] = {
+    tag: huks.HuksTag.HUKS_TAG_PURPOSE,
+    value:
+    huks.HuksKeyPurpose.HUKS_KEY_PURPOSE_SIGN
+}
+signProperties[2] = {
+    tag: huks.HuksTag.HUKS_TAG_KEY_SIZE,
+    value: huks.HuksKeySize.HUKS_RSA_KEY_SIZE_2048,
+}
+signProperties[3] = {
+    tag: huks.HuksTag.HUKS_TAG_PADDING,
+    value: huks.HuksKeyPadding.HUKS_PADDING_PSS,
+}
+signProperties[4] = {
+    tag: huks.HuksTag.HUKS_TAG_DIGEST,
+    value: huks.HuksKeyDigest.HUKS_DIGEST_SHA1,
+}
+signProperties[5] = {
+    tag: huks.HuksTag.HUKS_TAG_RSA_PSS_SALT_LEN_TYPE,
+    value: huks.HuksRsaPssSaltLenType.HUKS_RSA_PSS_SALT_LEN_MAX,
+}
+let signOptions = {
+    properties: signProperties,
+    inData: inData
+}
+
+huks.initSession(keyAlias, signOptions);

+
+## cl.huks.2 Resolved the Issues in Storage or Export of Derived or Agreed Keys
+
+Before the change, the HUKS supports storage and export of derived keys and agreed keys, which poses security risks.
+
+After the change, the application needs to pass in **HuksKeyStorageType** for key derivation or key agreement. Only storage or export is allowed at a time. If this parameter is not passed in, both storage and export are supported by default, which poses security risks and is not recommended.
+
+**Change Impact**
+
+Behaviors of released JavaScript APIs have been changed.
+
+**Key API/Component Changes**
+
+Released JavaScript APIs remain unchanged, but the parameter set passed to the APIs are changed.
+
+**Adaptation Guide**
+
+For more information, see [HUKS Development](../../../application-dev/security/huks-guidelines.md) and [HUKS](../../../application-dev/reference/apis/js-apis-huks.md).
+
+## cl.huks.3 Adding Tags for Fine-grained User Identity Access Control
+
+Added **HUKS_TAG_KEY_AUTH_PURPOSE** to **HuksTag** for fine-grained user identity access control. This tag specifies the user identity authentication used for specific algorithm. 
+
+**Change Impact**
+
+The new HuksTag does not affect existing APIs.
+
+**Key API/Component Changes**
+
+**HuksTag** is added with **HUKS_TAG_KEY_AUTH_PURPOSE** to support fine-grained user identity access control.
+
+**Adaptation Guide**
+
+For more information, see [Fine-grained User Identity Authentication](../../../application-dev/security/huks-guidelines.md#fine-grained-user-identity-authentication) and [HuksTag](../../../application-dev/reference/apis/js-apis-huks.md#hukstag).
