History

Martin Habovstiak a92d49fe33 Implement `CompressedPublicKey` P2WPKH requires keys to be compressed which introduces error handling even in cases when it's statically known that a key is compressed. To avoid it, this change introduces `CompressedPublicKey` which is similar to `PublicKey` except it's statically known to be compressed. This also changes relevant code to use `CompressedPublicKey` instead of `PublicKey`.		2023-12-12 15:16:16 +01:00

Running

To run the embedded test, first prepare your environment:

sudo ./scripts/install-deps
rustup +nightly target add thumbv7m-none-eabi

Then:

source ./scripts/env.sh && cargo +nightly run --target thumbv7m-none-eabi

Output should be something like:

heap size 524288
secp buf size 66240
Seed WIF: L1HKVVLHXiUhecWnwFYF6L3shkf1E12HUmuZTESvBXUdx3yqVP1D
Address: bc1qpx9t9pzzl4qsydmhyt6ctrxxjd4ep549np9993

Note that this heap size is required because of the amount of stack used by libsecp256k1 when initializing a context.

Cleanup

After sourcing scripts/env.sh and before building again using another target you'll want to unset RUSTFLAGS otherwise you'll get linker errors.
