🧹 Nitpick comments (5)
pkg/auth/token.go (1)
9-13: Consider adding documentation for the Token struct.The struct fields and their relationships aren't immediately clear from the names. Consider adding documentation to explain the purpose and relationship between
Username,Public, andPrivatefields.+// Token represents authentication credentials with a username and public/private key pair. +// Username: The user identifier (lowercase alphabetic, min 5 chars) +// Public: The public token derived from hashing the private token +// Private: The private token/seed used for validation type Token struct { Username string `validate:"required,lowercase,alpha,min=5"` Public string `validate:"required,min=10"` Private string `validate:"required,min=10"` }.env.example (1)
16-18: Address formatting and ordering issues flagged by static analysis.The static analysis tool identified several issues with the environment variable definitions:
- Remove unnecessary quotes from empty values
- Fix key ordering for consistency
# --- App super admin credentials -ENV_APP_TOKEN_USERNAME="" -ENV_APP_TOKEN_PUBLIC="" -ENV_APP_TOKEN_PRIVATE="" +ENV_APP_TOKEN_PRIVATE= +ENV_APP_TOKEN_PUBLIC= +ENV_APP_TOKEN_USERNAME=Note: The reordering follows the static analysis tool's alphabetical ordering suggestion, though the current order may be more logical for users.
cli/main.go (2)
15-15: Consider dependency injection over global variables for better testability.The global
guardvariable makes unit testing more difficult and creates tight coupling between components.Consider refactoring to pass the guard as a parameter:
-var guard gate.Guard -var environment *env.Environment -func init() { - secrets, _ := boost.Spark("./../.env") - - environment = secrets - guard = gate.MakeGuard(environment.App.Credentials) -} -func main() { +func main() { + secrets, err := boost.Spark("./../.env") + if err != nil { + cli.Errorln("Failed to load environment: " + err.Error()) + os.Exit(1) + } + + guard := gate.MakeGuard(secrets.App.Credentials)
33-36: Consider graceful error handling instead of hard exit.Using
os.Exit(1)prevents deferred functions from running and makes testing more difficult.Consider returning an error or using a more graceful exit strategy:
if guard.Rejects() { cli.Errorln("Invalid credentials") - os.Exit(1) + return }cli/gate/guard.go (1)
26-26: Clarify the naming inconsistency between prompt and storage.The prompt asks for "public token" but the input is stored as
salt, which could be confusing.Consider either:
- Changing the prompt to match the field name:
cli.Warning("Type the salt: ")- Or renaming the field to match the prompt:
publicToken stringinstead ofsalt string

22-22: Good refactoring to use centralized helper.The migration from a local
clearScreenfunction to the centralizedcli.ClearScreen()improves code reusability and maintainability.env/app.go (2)
3-3: Good addition of the auth package import.The import is correctly added to support the new
auth.Tokentype.
10-14: Clean refactoring to use the new token structure.The replacement of the nested admin struct with a single
auth.Tokenfield simplifies the structure while maintaining proper validation. This aligns well with the overall authentication refactoring.boost/boost.go (3)
64-68: Excellent input sanitization with TrimSpace.The consistent use of
strings.TrimSpace()for all token fields helps prevent issues with accidental whitespace in environment variables.
71-87: Comprehensive input sanitization applied consistently.Good practice applying
strings.TrimSpace()to all environment variable values throughout the configuration. This prevents common issues with trailing/leading whitespace in environment files.Also applies to: 90-103
113-115: Verify that auth.Token validation is properly implemented.The validation logic has switched from validating an admin user to validating the token struct. Ensure the
auth.Tokentype has proper validation tags and theIsValid/IsInvalidmethods are correctly implemented.#!/bin/bash # Description: Check if auth.Token struct has proper validation and methods # Search for the auth.Token struct definition and its validation methods ast-grep --pattern 'type Token struct { $$$ }' echo "=== Token validation methods ===" ast-grep --pattern 'func ($_ Token) IsValid($$$) $$$' ast-grep --pattern 'func ($_ Token) IsInvalid($$$) $$$' echo "=== Token validation tags ===" rg -A 10 'type Token struct'

1-10: LGTM! Clean package structure and imports.The package declaration and imports are well-organized and include all necessary dependencies for the authentication guard functionality.
12-16: Well-designed Guard struct with appropriate encapsulation.The Guard struct properly encapsulates the authentication state with:
- A salt pointer for storing user input
- An auth.Token for credential validation
- A buffered reader for input handling
The use of a pointer for salt allows tracking whether input has been captured.
18-23: Simple and correct constructor implementation.The MakeGuard function properly initializes the Guard with the provided token and sets up the input reader from stdin.
35-41: Excellent input validation addressing security concerns.The validation checks properly address the security recommendations from previous reviews:
- Empty input validation prevents bypass attempts
- Length limit (1024 characters) prevents potential buffer overflow or DoS attacks
- Clear, actionable error messages
This implementation effectively mitigates the security risks identified in past reviews.
48-56: Robust authentication logic with proper null checking.The Rejects method correctly:
- Checks if salt has been captured (null check)
- Dereferences the salt safely after null check
- Delegates validation to the token's IsInvalid method
The logic flow ensures authentication cannot be bypassed if input hasn't been captured.
