Summary
Stubbed cryptography without warnings
Details
The manzana crate appears to be a work-in-progress module for the Apple Silicon chips' features, including the Secure Enclave.
This crate's description and READMEs make no hint at the fact that the SecureEnclaveSigner type is a stubbed implementation that does not actually perform any cryptographic operations, and instead returns fixed values.
Unsuspecting users of the crate, who may not check the source code, receive no warning about this and may believe they are using a secure implementation when they are not.
There are currently (as of 2026-04-07) no versions of the crate that contain either a real implementation, or a warning about the stubbed cryptography.
