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 cd19f3144356d01753e62962ea0362e33eda2b1b
./scripts/verify-hash --ii-hash c2bd369b53d972e265cf1fd2755340101e83d097b1ae1b40d7314e04d7a5d476

Make sure to compare the hashes also with the proposal payload when verifying canister upgrade proposals.
