This piece marks the third installment in our ongoing series analyzing compelled decryption laws. As digital evidence continues to play a central role in modern investigations, legal systems worldwide are actively addressing the friction between encrypted devices and law enforcement access. For this chapter, our geographic focus shifts to East Asia. The region provides a highly practical comparative landscape for observing how neighboring jurisdictions weigh the technical demands of modern forensics against individual procedural rights. To map these diverse approaches, the following sections review the current legal mechanisms in mainland China, Hong Kong, Taiwan, Japan, and South Korea.

The first part of this series examined jurisdictions that have adopted a coercive approach to cryptographic barriers. Nations such as the United Kingdom, Australia, and France navigate the practical hurdles of end-to-end encryption through statutory workarounds. Rather than attempting to break the encryption itself, these legal systems apply pressure directly to the device owner – even if the owner is the suspect. By treating the refusal to provide decryption keys or passwords as a standalone criminal offense, they effectively bypass the technical roadblock. Under this model, non-compliance triggers its own set of penalties, entirely separate from the underlying investigation.
