About:
PortableLibxcrypt is a modern, portable implementation of the crypt(3) password hashing function. It provides strong support for legacy hashing algorithms like DES and MD5, as well as modern methods like bcrypt and SHA-2. This library allows applications to securely handle and verify user passwords across different Unix-like systems.

Key Features:

Support for legacy (DES, MD5) and modern (bcrypt, SHA-2) hashing
Highly portable across various Unix-like operating systems
Drop-in replacement for system crypt(3) libraries
Actively maintained with a focus on security and correctness

Use Cases:

Adding secure password hashing capabilities to C/C++ applications
Verifying legacy password hashes in system migration tools
Building authentication systems that require cross-platform compatibility

Alternatives:

OpenSSL libcrypto – Provides hashing functions but is a much larger and more complex dependency focused on general cryptography.
Libsodium – A modern cryptography library focused on high-level, secure-by-default primitives, not specifically on the legacy crypt(3) standard.
