Full release notes

Wasm Verification

To build the wasm modules yourself and verify their hashes, run the following commands from the root of the Internet Identity repository:

git pull  # to ensure you have the latest changes.
git checkout db8200dc4932df99c23a41232547f11a551164c3
./scripts/verify-hash \
    --ii-hash 897d2f2a125059aabf2eb0c4bb875b19a8873b71c4dbc8c0d13c174e5c1708b9 \
    --archive-hash d322bb6f05d1d0ba9e4b206846c9e61efc4d7d5cd578b2fee99006255572abfb

Backend Argument Verification

Run the following command to verify the backend upgrade argument hash:

didc encode -d ./src/internet_identity/internet_identity.did -t '(opt InternetIdentityInit)' '(null)' | xxd -r -p | sha256sum

The output should match the argument hash.
