+Secure Element SE05x
+====================
+
+.. contents:: :local:
+
+The Secure Element `SE050 <https://www.nxp.com/products/SE050>`__ is a tamper-resistant chip by NXP Semiconductors that provides advanced security features. It offers hardware-based security functions including cryptographic operations, secure key storage, and protection against physical and logical attacks. The SE05X Secure Element is certified to Common Criteria EAL 6+ security level and implements algorithms like RSA, ECC, AES, and SHA, making it ideal for the Nitrokey 3.
+
+PIV uses the Secure Element. OpenPGP Card can be configured to use the Secure Element or not in which case a software-only implementation is used. Passwords and FIDO2 don't use the Secure Element, but it is used for specific use cases, like additional randomness.
+
+Activation/Deactivation for OpenPGP
+-----------------------------------
+The Secure Element is enabled by default if no cryptographic key in OpenPGP Card and PIV is already saved on the device. 
+This is automatically the case after resetting the OpenPGP Card or the whole Nitrokey. Manually activating the Secure Element for the OpenPGP Card will delete all existing keys.
+
+To check whether the Secure Element for OpenPGP is activated run:
+
+* nitropy nk3 get-config opcard.use_se050_backend
+
+To enable the Secure Element:
+
+* nitropy nk3 set-config opcard.use_se050_backend true
+
+To disable the Secure Element: 
+
+* nitropy nk3 set-config opcard.use_se050_backend false
