14-38: LGTM with a minor suggestion for error handlingThe
PubKeyToProtofunction is well-implemented and follows good practices:
- Clear and descriptive function name
- Comprehensive documentation
- Proper error handling for unsupported key types
- Follows the Uber Go Style Guide
A minor suggestion to improve error handling:
Consider using a custom error type or error code for unsupported key types. This would make it easier for callers to programmatically handle this specific error case. For example:
var ErrUnsupportedKeyType = errors.Register(ModuleName, 2, "unsupported key type") // In the default case of the switch statement return nil, errors.Wrapf(ErrUnsupportedKeyType, "cannot convert %v to proto public key", pk)This approach allows for more granular error handling while maintaining the context provided by
errors.Wrapf.

41-69: LGTM with a minor suggestion for error handlingThe
PubKeyFromProtofunction is well-implemented and follows good practices:
- Clear and descriptive function name
- Comprehensive documentation
- Proper error handling for unsupported key types
- Follows the Uber Go Style Guide
- Symmetric implementation to
PubKeyToProto, which enhances consistencyA minor suggestion to improve error handling:
Similar to the suggestion for
PubKeyToProto, consider using a custom error type or error code for unsupported key types. This would make it easier for callers to programmatically handle this specific error case. For example:var ErrUnsupportedKeyType = errors.Register(ModuleName, 2, "unsupported key type") // In the default case of the switch statement return cryptokeys.JSONPubkey{}, errors.Wrapf(ErrUnsupportedKeyType, "cannot convert %v from proto public key", pk)This approach allows for more granular error handling while maintaining the context provided by

131-150: LGTM with a minor suggestion for improvementThe new
extractPrivKeyFromLocalfunction is well-implemented and documented. It correctly handles potential errors and follows good practices for private key extraction.A minor suggestion for improvement:
Consider wrapping the
ErrPrivKeyNotAvailableerror with additional context. This can be done usingerrorsmod.Wrap:if rl.PrivKey == nil { - return nil, ErrPrivKeyNotAvailable + return nil, errorsmod.Wrap(ErrPrivKeyNotAvailable, "in extractPrivKeyFromLocal") }This change would provide more context in error messages, potentially aiding in debugging.

550-594: Well-implemented mnemonic generation with room for improvement.The
NewMnemonicfunction is well-structured and correctly implements mnemonic generation and account creation. The comprehensive comments are excellent. Consider wrapping the errors returned frombip39.NewEntropyandbip39.NewMnemonicwith custom errors for better error handling and debugging.Consider updating the error handling as follows:
entropy, err := bip39.NewEntropy(defaultEntropySize) if err != nil { - return nil, "", err + return nil, "", errorsmod.Wrap(err, "failed to generate entropy") } mnemonic, err := bip39.NewMnemonic(entropy) if err != nil { - return nil, "", err + return nil, "", errorsmod.Wrap(err, "failed to generate mnemonic") }

734-831: Secure passphrase handling with room for improvement.The
newRealPromptfunction implements secure passphrase handling using bcrypt for hashing. The logic for both new passphrase creation and existing passphrase verification is well-implemented.However, there's a potential security concern:
The
maxPassphraseEntryAttemptsis defined as a package-level variable. Consider making it a configurable parameter to allow for different security policies in various contexts.-var maxPassphraseEntryAttempts = 3 + +func newRealPrompt(dir string, buf io.Reader, maxAttempts int) func(string) (string, error) { + if maxAttempts <= 0 { + maxAttempts = 3 // Default value + } return func(prompt string) (string, error) { // ... existing code ... - if failureCounter > maxPassphraseEntryAttempts { + if failureCounter > maxAttempts { return "", ErrMaxPassPhraseAttempts } // ... rest of the existing code ... } }This change allows for more flexible security configurations while maintaining a sensible default.

932-960: Robust migration function with room for improvement in error reporting.The
MigrateAllfunction effectively migrates legacy key information to the new Record format. The use of sorting for consistent results is a good practice.Consider aggregating errors instead of just printing them to stderr. This would provide a more comprehensive view of any issues encountered during migration. Here's a suggested improvement:
+import "go.uber.org/multierr" func (ks keystore) MigrateAll() ([]*Record, error) { // ... existing code ... + var errs error for _, key := range keys { // ... existing code ... rec, err := ks.migrate(key) if err != nil { - fmt.Fprintf(os.Stderr, "migrate err for key %s: %q\n", key, err) + errs = multierr.Append(errs, fmt.Errorf("migrate err for key %s: %w", key, err)) continue } recs = append(recs, rec) } - return recs, nil + return recs, errs }This change allows the caller to handle all migration errors comprehensively.

379-421: Well-documented and properly implemented signing function.The
Signfunction is well-structured and correctly handles different key types (local, ledger, and multi/offline). The comprehensive comments explaining the function's purpose, parameters, and return values are particularly commendable.

💡 Codebase verification
Inconsistency Between Comment and Implementation
The comment mentions using btcec to remove the dependency on tendermint/crypto/secp256k1. However, the actual implementation still utilizes secp for public key derivation:
ecPub := secp.PrivKeyFromBytes(privKeyBytes[:]).PubKey()pubkeyBytes := ecPub.SerializeCompressed()
Please update the implementation to use btcec as intended or revise the comment to accurately describe the current usage of secp.
🔗 Analysis chain
Clarify btcec usage and improve comment
The comment indicates that btcec is now being used to remove the dependency on tendermint/crypto/secp256k1, which is a good practice for reducing external dependencies. However, the actual implementation using btcec is not visible in this diff.
- Please clarify how
btcecis being used in the current implementation. - Consider improving the comment to explain the specific
btcecfunctions or methods being used for public key derivation. - Ensure that the comment accurately reflects the current implementation.
To verify the actual implementation, please run the following script:
This will help ensure that the comment accurately reflects the code and that btcec is being used as intended.
