如何生成hash签名？

Question

I am using twilio sdk to integrate sms verification with my android app, twilio asks me to register hash signature of my app and non of ways to generate hash signature worked, always says it is invalid hash signature this is the path that twilio wants the hash签名

Answer 1

用户在 android studio 终端中使用以下命令生成发布密钥哈希

keytool -exportcert -alias [aliasname] -keystore [your app keystore path] | openssl sha1 -binary | openssl base64

以及您项目中的以下代码以获取开发密钥哈希

try {
    android.content.pm.PackageInfo info = getPackageManager().getPackageInfo(
            "com.apps.sonictonic",
            android.content.pm.PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures) {
        java.security.MessageDigest md = java.security.MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        android.util.Log.d("KeyHash", "KeyHash:" + android.util.Base64.encodeToString(md.digest(),
                android.util.Base64.DEFAULT));

    }
} catch (android.content.pm.PackageManager.NameNotFoundException e) {

} catch (java.security.NoSuchAlgorithmException e) {

}

在您的 Activity onCreate() 中调用此方法并使用键“HashKey”在 logcat 中搜索您的键

public static void printHashKey(Context pContext) {
    try {
        PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            String hashKey = new String(Base64.encode(md.digest(), 0));
            Log.d("HashKey", "printHashKey() Hash Key: " + hashKey);
        }
    } catch (NoSuchAlgorithmException e) {
        Log.e(TAG, "printHashKey()", e);
    } catch (Exception e) {
        Log.e(TAG, "printHashKey()", e);
    }
}
