Secure Storage in Stackview

GiatriLalla — Tue, 13 Nov 2018 18:18:53 GMT

Good Day,

How can I retrieve a value and/ a key on Page 1 for instance, if it was stored using secure storage on the Startpage of a stackview layout. I have tried the value method however I am not successful. For example:

1. Start Page would look something like

TextField {

id: key

placeholderText: "Enter key"

}

TextField {

id:value

placeholderText: "Enter value"

anchors.left: key.right

}

//Click on the button to store data into keychain

Button {

id: SecureButton

text: qsTr ("Secure Data")

anchors.left: key.bottom

onClicked: {

SecureStorage.setValue(key.text, value.text)

}

2. Page 1 would look something like

//Click on button to retrieve data

Button {

id: retrieveButton

text: qsTr ("Retrieve Data")

anchors.top: secureButton.bottom

onClicked: {

retrieveData.text = qsTr("Value:") + SecureStorage.value(key.text)

}

//Display retrieved data

Text {

id:retrieveData

anchors.top: retrieveButoon.bottom

The information is being stored however I can not retrieve the information.

Giatri,

That should work, what is the error message? Did you make sure to have the import statement in the other page?

Please refer to this documentation page for Secure Storage and sample page.

Thank you,

Erwin.

I think the issue is that the key and value components with their associated properties aren't available to the Page 1 view in the stack since they are defined in Start Page and aren't global or passed to Page 1.

Good Morning,

How can I rectify this? Thank you.

Hi Giatri:

I'm not sure if there are security implications to these but you would need to either:

Create a string property on the App component and assign the key.value to it at the same time you set the SecureStorage.value. Then you can reference that 'global' string property in Page 1, or
Create a string property on each view, assign the key.value to the property in StartPage, then when you push Page1 onto the stack, assign the string property in Page 1 to the string property value on Start Page

So Number 1 above would look something like this:

App {
id: app
width: 400
height: 750

property string secureStorageKeyValue: ""

.....

//Click on the button to store data into keychain

Button {

id: SecureButton

text: qsTr ("Secure Data")

anchors.left: key.bottom

onClicked: {

app.secureStorageKeyValue = key.text;

SecureStorage.setValue(key.text, value.text);

}

Page 1

Button {

id: retrieveButton

text: qsTr ("Retrieve Data")

anchors.top: secureButton.bottom

onClicked: {

retrieveData.text = qsTr("Value:") + SecureStorage.value(app.secureStorageKeyValue);

}

Number 2

StartPage {

id: startPage

property string secureStorageKeyValue: ""

//Click on the button to store data into keychain

Button {

id: SecureButton

text: qsTr ("Secure Data")

anchors.left: key.bottom

onClicked: {

startPage.secureStorageKeyValue = key.text;

SecureStorage.setValue(key.text, value.text);

}

yourStackView.push( pageOneViewId, { "secureStorageKeyValue": startPage.secureStorageKeyValue } );

}

PageOne {

id: pageOne

property string secureStorageKeyValue: ""

Button {

id: retrieveButton

text: qsTr ("Retrieve Data")

anchors.top: secureButton.bottom

onClicked: {

retrieveData.text = qsTr("Value:") + SecureStorage.value(secureStorageKeyValue);

}

I had a chance to try both. I don't think any work for me. The second option gave alot of errors and the first is giving me the results as seen in the picture. I dont not know how to proceed. For privacy reasons, I do not want to share my code on here but if I can get that to you, maybe you'd be able to see the results yourself. Please advise accordingly. Thank you in advance.

I would recommend working with Esri Technical Support‌ for further troubleshooting.

I do not get any response from Esri Technical Support when I post a question.
