What are the symmetric key encryption techniques used by the enclave in quorum to encrypt the payload? The documentation of quorum mentions that the enclave uses a symmetric key to encrypt the payload but there is no mention of the algorithm that is used. Any leads would be highly appreciated.

This information is documented in several places and in the source code directly. Here is a link to an expanded explanation of what happens in the Tessera enclave: http://docs.goquorum.com/en/latest/Security/Framework/Quorum%20Network%20Security/Nodes/Permissioning/Network%20Permissioning/#enclave-encryption-technique. Tessera and c11n use NaCl and Argon2.
