  "message": "Add a hash_to_scalar variation of P-521\u0027s hash_to_field.\n\nDLEQ proofs for PMBTokens need a random oracle over scalars as well as\nfield elements. (Interestingly, draft-irtf-cfrg-voprf-03 section 5.1\ndoes not specify as strong of requirements, but then their reference\nimplementation does rejection sampling, so it\u0027s unclear.)\n\nReusing the hash_to_field operation so hash calls use the domain\nseparation tag consistently with other hash-to-curve operations seems\nprudent, so implement a companion function until the actual construction\nsolidifies.\n\nChange-Id: I92d807bfddcca26db690cce0a3da551143c25ff3\nReviewed-on: https://boringssl-review.googlesource.com/c/boringssl/+/40646\nReviewed-by: Steven Valdez \u003csvaldez@google.com\u003e\nCommit-Queue: Steven Valdez \u003csvaldez@google.com\u003e\n",
