The Delilah project, initiated by Alan Turing, aimed to create a compact portable device for voice encryption after World War II. Despite its high level of security and technological innovation, the project was soon abandoned as Turing moved to work on developing electronic computers. The discussions highlight the challenges of key synchronization in encryption, which was recognized even by Turing as complex. Some users mention the significance of making historical documents available to the public, contrasting this with contemporary practices of keeping such works hidden in private collections. Additionally, parallels are drawn between Turing's work and fictional representations of secure communication, affirming the ongoing interest in cryptography's history and developments.
