Secret writing.
Context
Many personal attributes and much valuable content are meant to be kept hidden from all but a chosen few. Encryption enables that. It also can enable Signing and Authentication, but those are addressed elsewhere.
Problems
- Encryption that cannot be broken by adversaries depends ultimately on one-way processes that cannot be determined by the result.
- Sometime the one-way functions turn out to be vulnerable. The most recent vulnerability was found with a combination of quantum computing an Schnor's algorithm. See the wiki page on Quantum Computing Threat for details and possible solutions.
