+### PERFORM PRIVACY OPERATION
+
+#### Description
+
+This command performs privacy operations as defined in EIP 1024 (https://ethereum-magicians.org/t/eip-1024-cross-client-encrypt-decrypt/505)
+
+It can return the public encryption key on Curve25519 for a given Ethereum account or the shared secret (generated by the scalar multiplication of the remote public key by the account private key on Curve25519) used to decrypt private data encrypted for a given Ethereum account
+
+All data can be optionally checked on the device before being returned.
