There always has to be a balance. Some countries have enacted laws to create an obligation to disclose encryption keys, etc. during criminal investigations in response to new technologies because now everyone has access to encryption methods that are essentially unbreakable without knowing the key. So while people have and should have the right not to incriminate themselves it is also reasonable to ensure that criminal investigations can still be (fairly) carried out... It was much easier when people could only hide their secrets in a safe. I believe even in the US one may be obligated to disclose keys. One big question is whether this should require a court order, which implies that the police must convince a judge that this is necessary and useful, or whether (as seems the case here?) the police themselves have that power, which is indeed more contentious.
