107-110: Consider adding logging for security-sensitive operations.Exporting private keys is a highly sensitive operation that should be logged for security auditing purposes. Consider adding appropriate logging when this method is called.
// ExportPrivateKeyObject implements the unsafeExporter interface. func (k *Keyring) ExportPrivateKeyObject(uid string) (types.PrivKey, error) { + // Log that a private key is being exported (consider logging caller information if possible) + // logger.Info("private key export operation requested", "key_uid", uid) return k.Keyring.(unsafeExporter).ExportPrivateKeyObject(uid) }
19-24: Document security implications of this feature.Given that this feature exports unarmored private keys, consider adding more detailed documentation about:
- Under what circumstances this should be used
- Security implications and risks
- Recommendations for secure handling of the exported keys
This will help guide users to understand when and how to use this feature safely.

19-24: Good interface definition for unsafe operations.The interface design with a clear "unsafe" prefix in its name appropriately signals the potential security implications of exporting unarmored private keys. The documentation is clear about its purpose.
26-26: Proper compile-time interface validation.Using the
var _ interfaceName = (*implementingType)(nil)pattern ensures theKeyringstruct implements theunsafeExporterinterface at compile time. This is a good Go practice to catch implementation errors early.
| // ExportPrivateKeyObject implements the unsafeExporter interface. | ||
| func (k *Keyring) ExportPrivateKeyObject(uid string) (types.PrivKey, error) { | ||
| return k.Keyring.(unsafeExporter).ExportPrivateKeyObject(uid) | ||

🛠️ Refactor suggestion
Add error handling for the type assertion.
The current implementation uses an unchecked type assertion which could panic at runtime if the underlying Keyring doesn't implement the unsafeExporter interface.
// ExportPrivateKeyObject implements the unsafeExporter interface.
func (k *Keyring) ExportPrivateKeyObject(uid string) (types.PrivKey, error) {
- return k.Keyring.(unsafeExporter).ExportPrivateKeyObject(uid)
+ unsafeExport, ok := k.Keyring.(unsafeExporter)
+ if !ok {
+ return nil, errors.New("underlying keyring does not support unsafe export operations")
+ }
+ return unsafeExport.ExportPrivateKeyObject(uid)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
