I am no expert, but "Signal rolling their own crypto" isn't the same as "X rolling their own crypto":
1. Folks spear-heading the Noise Protocol Framework (upon which Signal's protocol is based) are cryptographers [0].
2. They built upon existing standards for one specific purpose: Creating two-way secure channels [1].

- dbrgn 6y agoAs far as I know, the Signal protocol was developed for TextSecure back in 2013. Noise actually references the Double Ratchet Algorithm by Moxie and Trevor Perrin as an inspiration. Not the other way around. At some point in time, all now well-established cryptographers will have developed their first own cryptosystem, without already having established a good reputation. Whether or not someone develops a cryptosystem without being famous for cryptography work is simply not a good argument for discussing a cryptosystem. The properties of a cryptosystem are a good argument for discussing it.
