Well, not really:
United Kingdom — RIPA Part III (criminal penalties for refusal).
France — provisions allowing compelled decryption/key assistance with penalties.
India — IT Act §69 compels assistance in decryption; penalties for noncompliance.
Ireland — Criminal Justice (Offences Relating to Information Systems) Act 2017 allows demanding passwords/keys under warrant framework.
Australia — multiple mechanisms; broadly framed “assistance” authorities (and the later Assistance and Access framework focuses heavily on assistance obligations).
Finland — Coercive Measures Act compels “passwords and other such information,” with suspect/witness-style carveouts.
.. and those are Western countries. Won't even get into developing nations and their rules which are even worse.
Based on my quick research in "key disclosure law," it seems that (in the USA) this question is still mostly up in the air. So far, it seems that you cannot generally be compelled to supply your password, because that could be self-incrimination. HOWEVER, if the government is already aware of what the contents of the encrypted data is, and can prove that it's yours/you had access to it, they can legally compel you to supply your password, because you would not be additionally incriminating yourself. However, it seems like there hasn't been enough action in this area for the case law to completely settle and this question to be definitively answered.
