Google Chrome stores browser cookies in an SQLite database. The database has two tables, meta containing format and version metadata, and cookies with the contents of the cookies. The cookies table uses this schema:

-- To reproduce: sqlite path/to/Cookies .schema
CREATE TABLE cookies (
   creation_utc     INTEGER  NOT NULL,  -- microseconds since epoch
   host_key         TEXT     NOT NULL,  -- domain
   name             TEXT     NOT NULL,
   value            TEXT     NOT NULL,
   path             TEXT     NOT NULL,
   expires_utc      INTEGER  NOT NULL,  -- microseconds since epoch
   is_secure        INTEGER  NOT NULL,
   is_httponly      INTEGER  NOT NULL,
   last_access_utc  INTEGER  NOT NULL,
   has_expires      INTEGER  NOT NULL DEFAULT  1,
   is_persistent    INTEGER  NOT NULL DEFAULT  1,
   priority         INTEGER  NOT NULL DEFAULT  1,
   encrypted_value  BLOB              DEFAULT '',
   samesite         INTEGER  NOT NULL DEFAULT  -1,
   source_scheme    INTEGER  NOT NULL DEFAULT  0,

   UNIQUE (host_key, name, path)
);
