Speaking of cryptography, I've given up on setting up a Termux Python dev environment on an old Arm tablet, because some package has a dependency on the 'cryptography' module, which apparently requires the whole Rust toolchain to build. In a Python project. On a platform with limited storage. The documentation suggests pre-built binaries are an option, but I couldn't figure it out the last few times. It left me with a bad taste in my mouth.
