-### Android Profile for DICE
-
-The Android Profile for DICE is based on the [Open Profile for
-DICE](https://pigweed.googlesource.com/open-dice/+/refs/heads/main/docs/specification.md),
-with additional constraints for details that the Open Profile for DICE leaves
-intentionally underspecified. This section describes the differences from the
-Open Profile for DICE.
-
-#### Algorithms
-
-The choice of algorithm must remain consistent with a given certificate e.g. if
-SHA-256 is used for the code hash then the authority hash, config hash, etc.
-must also use SHA-256.
-
-* UDS and CDI key pairs:
-  * Ed25519 / P-256 / P-384
-* Hash algorithms (digests can be encoded with their natural size and do not
-  need to be the 64-bytes specified by the Open Profile for DICE):
-  * SHA-256 / SHA-384 / SHA-512
-* HKDF with a supported message digest for all key derivation
-
-#### Mode
-
-A certificate must only set the mode to `normal` when all of the following
-conditions are met when loading and verifying the software component that is
-being described by the certificate:
-
-* verified boot with anti-rollback protection is enabled
-* only the verified boot authorities for production images are enabled
-* debug ports, fuses, or other debug facilities are disabled
-* device booted software from the normal primary source e.g. internal flash
-
-The mode should never be `not configured`.
-
-Every certificate in the DICE chain will need to be have the `normal` mode in
-order to be provisioned with production certificates by RKP.
-
-#### Configuration descriptor
-
-The configuration descriptor is a CBOR map with the following optional fields.
-If no fields are relevant, an empty map should be encoded. The key value range
-\[-70000, -70999\] is reserved for the Android Profile for DICE.
-Implementation-specific fields may be added using key values outside of the
-reserved range.
