如何获取应用签名证书的hash值

Answer 1

当前支持获取本应用的“应用指纹”：

import bundleManager from '@ohos.bundle.bundleManager'; 
import hilog from '@ohos.hilog'; 
let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_SIGNATURE_INFO; 
try { 
  bundleManager.getBundleInfoForSelf(bundleFlags).then((data) => { 
    hilog.info(0x0000, 'testTag', 'getBundleInfoForSelf successfully. Data: %{public}s', JSON.stringify(data)); 
    console.log('SHA-256',data.signatureInfo.fingerprint) 
  }).catch(err => { 
    hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed. Cause: %{public}s', err.message); 
  }); 
} catch (err) { 
  hilog.error(0x0000, 'testTag', 'getBundleInfoForSelf failed: %{public}s', err.message); 
}

“应用指纹”实际上是证书的SHA-256摘要，可使用Java 数据证书的管理工具Keytool查看：
