## Download MTF OAuth credentials {#download-mtf-oauth-credentials}

When the project is successfully created, the Sandbox .P12 access credentials are available for download.

1. Click **Download PKCS#12 Keystore** to download a zip file containing the .p12 file required for OAuth authentication in MTF.
2. Click **Continue** . Note: You may want to record the keystore password and key alias for future use. The keystore password is used in conjunction with the .p12 file and Client ID for OAuth authentication.
3. Click **Confirm and Continue** to complete the MTF Setup process.

Note: Mastercard APIs use OAuth 1.0a with a request body hash as the security standard. The PKCS#12 keystore contains the private key used for signing requests. The key downloaded from our portal is generated inside your browser and is not be stored by Mastercard Developers. The public key matching the generated private key is uploaded to Mastercard Developers for signature verification purposes as part of the process. **Make sure to keep this file in a secure place.**

Create your encryption keys for your project through your [Developer Dashboard](https://developer.mastercard.com/dashboard).

3. Confirm your credentials. The keyalias-encryption-mc.p12 file downloads. You will use this file to decrypt the payload.

Note: For production, you will receive two p12 files. The keyalias-encryption.p12 is used for Oauth and the keyalias-encryption-mc.p12 is used for decrypting the payload.
