Missing 'crypto' package (parity with Go 1.26)

[1l0]

Go 1.26 introduced a new crypto package containing several core interfaces. However, this package is currently missing in TinyGo ^0.41.0, leading to compilation errors when using libraries that depend on the new standard library structure.

For local development, the package can be manually copied from the GOROOT to the TINYGOROOT:

cp $(go env GOROOT)/src/crypto/crypto.go $(tinygo env TINYGOROOT)/src/crypto/

I suggest including this file in the TinyGo to maintain compatibility with Go 1.26.

Do you have a failing test? The crypto package should use the stdlib version with additions from tinygo/src overlaid.

Maybe this is specific to Wasm. On my end, I had to copy the file manually.

$ tinygo version
tinygo version 0.42.0-dev-3b88a2cd darwin/arm64 (using go version go1.26.2 and LLVM version 20.1.1)
