Key Transparency


Key Transparency (KT) is a safe, publicly-auditable way to distribute public keys for end-to-end encryption. More generally, the same technology can also be used for tamper-evident logging, key usage detection, ensuring that a group of users agree on a shared value, and many other applications.

This effort aims to standardize a common protocol for Key Transparency that 1.) works for a large range of use-cases, 2.) provides clean security guarantees, 3.) is able to be thoroughly studied by security researchers, and 4.) has trustworthy open source implementations.
