# DarkForge Linux — Phase 3, Chapter 8.28: Libxcrypt
# ============================================================================
# Purpose:  Build libxcrypt, a modern replacement for the crypt() function
#           in glibc. Provides support for various password hashing algorithms
#           (MD5, SHA-256, SHA-512, bcrypt, etc.).
#           Required by shadow password utilities and system authentication.
# Inputs:   /sources/libxcrypt-4.4.38.tar.xz
# Outputs:  libxcrypt library in /usr/lib, headers in /usr/include
# Ref:      LFS 13.0 §8.28
# ============================================================================
