Note: the term snake oil in regards to cryptography has different connotations than it does in general use, implying naïveté/overconfidence rather than malice.
From the article above:
"Most products seem to fall into the middle category: well-meaning but insecure. I've talked about the reason in previous CRYPTO-GRAM essays, but I'll summarize: anyone can create a cryptography product that he himself cannot break. This means that a well-meaning person comes up with a new idea, or at least an idea that he has never heard of, cannot break it, and believes that he just discovered the magic elixir to cure all security problems. And even if there's no magic elixir, the difficulty of creating secure products combined with the ease of making mistakes makes bad cryptography the rule.
The term we use for bad cryptography products is "snake oil," which was the turn-of-the-century American term for quack medicine. It brings to mind traveling medicine shows, and hawkers selling their special magic elixir that would cure any ailment you could imagine."
