matejcik	ba365b5486	cosi: replace slow djb implementation of ed25519 with an optimized one ... from https://github.com/pyca/ed25519 This makes the calculations several orders of magnitude faster, which allows us to run the CoSi test in Travis. It also doesn't stop firmware update for several seconds while we validate the CoSi signatures. It's still essentially the same insecure implementation, fallible to all the same timing attacks, and it shouldn't be used for anything except validating public signatures of public data. But now it also takes about as much time as it should on modern hardware.	6 years ago

matejcik	54f1599a5a	regenerate license headers ... This clarifies the intent: the project is licenced under terms of LGPL version 3 only, but the standard headers cover only "3 or later", so we had to rewrite them. In the same step, we removed author information from individual files in favor of "SatoshiLabs and contributors", and include an AUTHORS file that lists the contributors. Apologies to those whose names are missing; please contact us if you wish to add your info to the AUTHORS file.	6 years ago

matejcik	886e269e2f	trezorlib: mark ed25519 impl as private	6 years ago
matejcik	db92b13f97	cosi: move things around ... ed25519raw is moved back to trezorlib ed25519cosi is renamed to cosi, and has a couple more functions, with the expectation that TrezorClient.cosi_* methods will move there. Also most code shouldn't need ed25519raw for anything, so it might get renamed to "_ed25519" to indicate that it's a private implementation. For now, I added a "verify" method to cosi, so that you don't need to call into ed25519raw.checkvalid. But trezor-core's keyctl is also using ed25519raw.publickey. I'm not sure if that's worth replicating in cosi, or whether to just leave it be, so I'm leaving it be for now. Importantly, new function "sign_with_privkey" does that math thing that was part of the selftest and is also explicitly listed in keyctl. (it's called sign_with_privkey because I expect to have a "sign" method here that calls into Trezor)	6 years ago
