Why We All Need To Agree That It Is Flat Out Unacceptable To Use RSA in 2019
An excerpt from a post on Trail of Bits: From major open source projects to exciting new proprietary software, we've seen it all. But one common denominator in all of these systems is that for some inexplicable reason people still seem to think RSA is a good cryptosystem to use. Let me save you a bit of time and money and just say outright -- if you come to us with a codebase that uses RSA, you will be paying for the hour of time required for us to explain why you should stop using it. RSA is an intrinsically fragile cryptosystem containing countless foot-guns which the average software engineer cannot be expected to avoid. Weak parameters can be difficult, if not impossible, to check, and its poor performance compels developers to take risky shortcuts. Even worse, padding oracle attacks remain rampant 20 years after they were discovered. While it may be theoretically possible to implement RSA correctly, decades of devastating attacks have proven that such a feat may be unachievable in practice.Read more of this story at Slashdot.
