# CSE library public key, location, and token

[View source](/online-payments/classic-integrations/classic-api-integration/client-side-encryption/cse-library-public-key-location-and-token.md)

**The Client-Side Encryption (CSE) Web integrations are being phased out**\
This means we are:

* No longer developing the CSE integration.
* Not accepting new CSE integrations.

Switch to one of our latest [Web integrations](/online-payments/build-your-integration/sessions-flow?platform=Web), to accept payments on your website.

Mobile integrations aren't affected.

For using the Client-Side Encryption (CSE) library, you need to obtain its public key, location, and library token.

To obtain these values, follow the instructions below:

1. Log in to your [Customer Area](https://ca-test.adyen.com/) using your company account.

2. Navigate to **Developers** > **API credentials**.

3. If you do not have an API credential yet, click **Add new credential.**\
   If you already have an API credential, search for this credential (for example, **ws\@Company.\[YourCompanyAccount]**)  in the list.

4. On the **Edit Web Service User** page, click the **Generate** button on the **Client-Side Encryption** panel:\

5. Copy **Public Key**, **Library location**, and **Library token** values to store them on your system:\

Note that these values will be changed once you switch your account from test to live .
