If you believe the open source producer claiming "I built from the published source, without any trojans" you have just as much reason to believe the closed-source producer claiming "I built the standard SHA1 algorithm without any trojans."

If somebody's going to build the april_1st code you wrote above into their binary, they're not going to show you that code, even if the project is a supposedly open source project.
