web-pinentry: a pinentry program that leverages Matrix and HTTP.

web-pinentry addresses the operational challenge of securely decrypting server passwords during bootup, particularly in remote or headless environments. By integrating with Matrix and HTTP, it offers a novel approach to secure credential entry, potentially enhancing automation and reducing manual intervention risks. This solution targets server administrators and DevOps teams, providing a more flexible and potentially more secure alternative to traditional `pinentry` methods, especially in distributed or cloud-native infrastructures where direct console access is limited. Its utility lies in bridging secure human interaction with automated server processes.
