String obfuscator
Obfuscate strings to make them harder to read
Configuration
Configure how to obfuscate your string
Use cases:
- Share tokens without revealing full content
- Display sensitive data in logs
- Show partial information for identification
Obfuscated Result
Your obfuscated string
TL;DR
What is String obfuscator?
String obfuscation makes a string difficult to read at a glance by replacing or rearranging characters. It is not encryption: the transformation is reversible and provides no cryptographic security. Its purpose is to obscure content from casual inspection, not from a determined adversary.
Common use cases
- ‣Log masking: replace sensitive values (API keys, tokens) with obfuscated strings in log output for sharing
- ‣UI redaction: display a partially hidden value (e.g. a credit card number as ****1234) in a preview
- ‣Spoiler text: lightly obscure content to prevent accidental reading
Frequently asked questions
Is obfuscation the same as encryption?
No. Obfuscation has no key and provides no security guarantee. Anyone who understands the obfuscation method can reverse it. Use encryption (AES-256) when the data must actually be kept secret.
When is obfuscation appropriate?
Obfuscation is appropriate when you need to reduce accidental exposure (a colleague glancing at your screen, a screenshot in a bug report) rather than prevent a determined attacker. For actual secrets, use proper encryption or a secrets manager.
