Java String Encryptor/Obfuscator
Obfuscate Java strings using 5 powerful techniques: Unicode escape sequences, hex byte arrays with new String(), Base64 decoding with java.util.Base64, XOR-encrypted byte arrays, and StringBuilder split concatenation. Each method generates valid Java code that produces the original string at runtime.
Java Control Flow Flattener
Flatten Java control flow into a switch-based dispatcher obfuscation pattern online free. Transform if/else, for, while, and do-while loops into a flat dispatcher structure with configurable depth (Basic/Standard/Deep). Paste Java code or load a sample, see size analysis. All browser-local, no signup required.
