Protect addresses, phone numbers, and emails with masking and cipher methods for privacy
Replaces part of the data with asterisks. Maintains partial readability for identification.
This tool applies client-side transformations to sensitive data. No data is ever sent to a server. Two methods are available: Masking replaces characters with asterisks, Cipher applies a Caesar substitution.
Protect sensitive information in shipping labels, internal documents, and shared content while maintaining necessary readability.
Answers about obfuscation methods, security guarantees, and choosing between masking and cipher techniques.
Is my data secure?
Yes, all processing happens entirely in your browser. Your data never leaves your device. No data is sent to any server, ensuring complete privacy.
What's the difference between masking and cipher?
Masking replaces characters with asterisks while maintaining partial readability. Cipher encodes the entire text using Caesar substitution, making it unreadable without knowing the method.
Can I recover the original data?
For masking, partial data is visible. For cipher, you can recover the original if you know it's a Caesar cipher and the shift amount. These methods are for privacy, not encryption.
When should I use each method?
Use masking for labels where partial readability is helpful (e.g., delivery confirmation). Use cipher for internal documents where only authorized personnel should be able to read the data.
Recommendations for selecting the right obfuscation method based on your privacy and readability needs.
