-## Running Tests
-
-This package depends on tests that require crypto keys too large to inline into
-a peer ID. These tests generate 512bit RSA keys for speed purposes. To run
-these tests successfully, you must set the environment variable
-`LIBP2P_ALLOW_WEAK_RSA_KEYS` to any non-empty value, e.g. `1`.
-
-```bash
-$ LIBP2P_ALLOW_WEAK_RSA_KEYS=1 go test
-```
-
 ## Usage
 
 Go to https://godoc.org/github.com/libp2p/go-libp2p-kad-dht.
