Understanding the Cardano Message Signing Process

Before diving into the specifics of the error, it’s crucial to understand the fundamental process of Cardano message signing. When you sign a message using your hardware wallet, you are essentially using your private key to create a digital signature that verifies your identity and the integrity of the message. This process is vital for various applications, including authenticating transactions, logging into services, and proving ownership of assets. The hardware wallet plays a critical role in this process by securely storing your private key and performing the cryptographic operations necessary for signing without exposing the key to your computer or other devices. The path specified in the signing request, such as m/1852'/1815'/0'/2/0, is a crucial element. This path, also known as a derivation path, tells the wallet which key to use for signing. It's a hierarchical structure that pinpoints a specific key within the wallet's key tree. A mismatch or an invalid path can lead to the "Invalid path" error, preventing the signing process from completing successfully.

Key Components Involved in Message Signing

  1. The Message: The data you want to sign. It could be anything from a login request to a transaction authorization.
  2. The Path (Derivation Path): A string that specifies the location of the private key within the hardware wallet’s hierarchical key structure. This path is crucial for the wallet to identify the correct key to use for signing.
  3. The Private Key: Stored securely within the hardware wallet, the private key is used to generate the digital signature.
  4. The Public Key: Derived from the private key, the public key is used to verify the signature.
  5. The Signature: The result of applying the private key to the message using a cryptographic algorithm. This signature is unique to the message and the private key.

Understanding these components is essential for troubleshooting any issues related to message signing. The "Invalid path" error, in particular, highlights the importance of the derivation path in the signing process. A correct and valid path is necessary for the hardware wallet to locate the correct private key and generate the signature successfully. Without it, the signing process will fail, resulting in the error message.

Decoding the "Failure_Error, Invalid Path" Error

The "Failure_Error, Invalid path" error is a common issue encountered when using hardware wallets like the OneKey Classic 1S for signing messages. This error indicates that the device is unable to locate the specified key within its storage using the provided derivation path. The derivation path, such as m/1852'/1815'/0'/2/0, acts as a map, guiding the wallet to the correct private key needed for signing. When this path is incorrect, malformed, or unsupported by the device's firmware, the signing process grinds to a halt, and the dreaded error message appears. This error can manifest in various scenarios, such as when interacting with decentralized applications (dApps), confirming transactions, or even during the login process on certain platforms. The root cause often lies in inconsistencies between the path expected by the software and the paths supported by the hardware wallet's firmware. Understanding the nuances of derivation paths and their compatibility with different wallets and applications is crucial for resolving this issue.

Common Causes of the "Invalid Path" Error
