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 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 ValidateUsername ¶
ValidateUsername validates that a username meets all requirements
Types ¶
type PaddingCalculator ¶
type PaddingCalculator struct{}
PaddingCalculator handles file padding calculations for privacy
func NewPaddingCalculator ¶
func NewPaddingCalculator() *PaddingCalculator
NewPaddingCalculator creates a new padding calculator instance
func (*PaddingCalculator) CalculatePaddedSize ¶
func (p *PaddingCalculator) CalculatePaddedSize(originalSize int64) (int64, error)
CalculatePaddedSize returns the padded size for a given file size using percentage-based block alignment with randomized jitter.
Block size = 2% of file size (minimum 64KB). The file is rounded up to the nearest block boundary, then random jitter (0 to 10% of block size) is added. This gives a consistent worst-case padding overhead of ~2.2% for files above 3.2MB, with the 64KB minimum floor providing size obfuscation for smaller files at negligible absolute cost.
func (*PaddingCalculator) GeneratePaddingBytes ¶
func (p *PaddingCalculator) GeneratePaddingBytes(size int64) ([]byte, error)
GeneratePaddingBytes generates cryptographically secure random padding bytes
func (*PaddingCalculator) GetPaddingSize ¶
func (p *PaddingCalculator) GetPaddingSize(originalSize, targetSize int64) int64
GetPaddingSize calculates how much padding is needed given original and target sizes
