With cryptographic bugs, it’s often hard to cross the mental bridge between “it is theoretically broken” to “it can be easily exploited”.
Well, take a look at what can happen with home-brewed cryptosystems in the wild: numerous bugs in the cryptography implementation allow locating, tracking, and even stealing other people’s "toy cars"!
An overview of the coming updates that will be in Go 1.20. It will include the crypto/ecdh package, making progress on moving math/big out of the security perimeter, and a batch of crypto/tls work.
If you didn't know, Filippo Valsodo has been in charge of cryptography and security on the Go team at Google and now becoming a professional Open Source maintainer. So if your company depends on Go and its cryptography libraries, consider sponsoring Filippo's maintenance work.
