A header-only C++17 library that encrypts string literals at compile time using XOR with 64-bit keys and vectorized (SSE/AVX) inlined decryption. It hides strings from static analysis by embedding encrypted data directly into code rather than .rdata sections.

Use cases

• hide string literals from reverse engineering
• obfuscate strings in C++ binaries
• prevent static analysis of embedded strings
• encrypt compile-time constants in C++
• protect malware-unrelated software from string-based scanning
• avoid plaintext strings in .rdata section

When to choose

• you need compile-time string obfuscation in C++ with zero runtime dependencies
• you want decryption fully inlined and vectorized for performance
• you need cross-platform support for GCC, Clang, and MSVC

When to avoid

• you need strong cryptographic security rather than obfuscation
• your project targets compilers older than GCC 7.1 or Clang 5.0
• you need runtime-configurable encryption keys
• your CPU lacks SSE and you cannot tolerate AVX-only paths
