  "message": "[otp_ctrl] Improve security of Merkle-Damgard digest\n\nThe one-way function used in the Merkle-Damgard digest function was\npreviously constructed with a PRESENT cipher primitive only.\nThis commit improves this one way function by using the Davies-Meyer\nconstruction, which additionally chains the digest states with an\nXOR operation.\n\nSigned-off-by: Michael Schaffner \u003cmsf@opentitan.org\u003e\n",
