Delete a key

Reading or writing key definitions requires an admin key.

Problem

You need to delete a key from the current database.

Solution

Use the function:Delete[] function:

try
{
    Value result = await adminClient.Query(
        Delete(Ref(Keys(), "1"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
ObjectV(ref: RefV(id = "1", collection = RefV(id = "keys")),ts: LongV(1631728225420000),role: StringV(admin),hashed_secret: StringV($2a$05$W5HR2L6lJQ/fLllyqpvVw.knusY0BqHVYztLznZsBF8lvXqGNCE/S),data: ObjectV(team: StringV(Engineering)))
result, err := adminClient.Query(
	f.Delete(f.Ref(f.Keys(), "1")))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[data:map[team:Engineering] hashed_secret:$2a$05$6APJkVtuIG9nrNzsfnLt4e.D.wVqCLK6sQU2GkqOWov4dSrScgaXK ref:{1 0xc00009b860 0xc00009b860 <nil>} role:admin ts:1631728147980000]
System.out.println(
    adminClient.query(
        Delete(Ref(Keys(), "1"))
    ).get());
{ref: ref(id = "1", collection = ref(id = "keys")), ts: 1631728316710000, role: "admin", hashed_secret: "$2a$05$DDEdo7/UaZmkwaz/enpFDOMljr39oHsZEIE4mZFH7cPQVOHFGGTnW", data: {team: "Engineering"}}
adminClient.query(
  q.Delete(q.Ref(q.Keys(), '1'))
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
{
  ref: Ref(Keys(), "1"),
  ts: 1631728043380000,
  role: 'admin',
  hashed_secret: '$2a$05$kdsBSqgV/EoShNny0aoCMuccN94tHSqJOuTTbJ58SRIrHixS/MUhm',
  data: { team: 'Engineering' }
}
result = adminClient.query(
  q.delete(q.ref(q.keys(), "1"))
)
print(result)
{'ref': Ref(id=1, collection=Ref(id=keys)), 'ts': 1631728104560000, 'role': 'admin', 'hashed_secret': '$2a$05$Lo9hpVwalRvyIFbhIZbgy.Y/PEoDjAM/5RzQiVmJoJuiVic5kr/IK', 'data': {'team': 'Engineering'}}
Delete(Ref(Keys(), '1'))
{
  ref: Ref(Keys(), "1"),
  ts: 1631727967280000,
  role: 'admin',
  hashed_secret: '$2a$05$qbGb.Xk0N.7Dnu9LP6MF7up7bgAlR1RiJyyZ4zaRXT521OWwL0Sam',

Discussion

Once a key has been deleted, any client still using the key’s secret can no longer execute queries.
