Greg, When someone else discovers an issue with your product and you find out about it - you should be thankful. They could have just as easily sold the bug silently to the intelligence community - or let you otherwise continue to produce insecure software. In fact "irresponsible disclosure" sup

Hello Greg. I tried out Espionage.app and it was easy to distinguish real encrypted images from fake images via filesystem metadata. I don't think Espionage offers any realistic notion of plausible deniability, especially against "totalitarian regimes" as the webpage claims. This took no special s
