Functions ¶
func GetEnvironmentName ¶
func GetEnvironmentName() string
GetEnvironmentName returns the current environment name
func GetJWTTokenLifetime ¶
GetJWTTokenLifetime returns the JWT token lifetime from environment variables Defaults to 30 minutes if not set or invalid
func GetUsernameValidationRules ¶
func GetUsernameValidationRules() string
GetUsernameValidationRules returns a human-readable description of username rules
func IsDevAdminAccount ¶
IsDevAdminAccount checks if a username is a development admin account
func IsHexString ¶
IsHexString checks if a string contains only hexadecimal characters
func IsProductionEnvironment ¶
func IsProductionEnvironment() bool
IsProductionEnvironment checks if the application is running in production
func IsValidUsername ¶
IsValidUsername returns true if the username is valid, false otherwise
func SanitizeUsername ¶
SanitizeUsername performs basic sanitization on a username Note: This is for display purposes only, not for bypassing validation
func ValidatePasswordComplexity ¶
ValidatePasswordComplexity checks if a password meets complexity requirements. Requirements: 14+ chars, 1+ upper, 1+ lower, 1+ digit, 1+ special.
func ValidateUsername ¶
ValidateUsername validates that a username meets all requirements
Types ¶
