Filament Column Obfuscation

A Filament plugin that allows you to easily obfuscate sensitive data in table columns, protecting personally identifiable information (PII) and other confidential data in your Filament admin panels.

Features

• Mask sensitive data in Filament table columns (emails, phone numbers, addresses, etc.)
• Customizable obfuscation patterns (show first/last X characters, use custom characters)
• Toggle visibility with click/hover actions
• Simple integration with existing Filament tables

Planned Features

• Role-based permissions for viewing unobfuscated data

Example

use RandomParanoia\FilamentColumnObfuscation\Columns\ObfuscatedColumn;

// In your Filament resource or table
public static function table(Table $table): Table
{
    return $table
        ->columns([
            // Basic usage - masks most characters
            ObfuscatedColumn::make('email')
                ->label('Email Address'),

            // Advanced usage with customization
            ObfuscatedColumn::make('phone_number')
                ->obfucastionPattern('phone')
                ->label('Phone Number')
                ->showFirstChars(3)
                ->showLastChars(2)
                ->obfuscationCharacter('*')
                ->revealOnClick(),
        ]);
}
