LGPL Crypto library - Windows development

 libgcrypt contains cryptographic functions. Many important free
 ciphers, hash algorithms and public key signing algorithms have been
 implemented:
 .
 Arcfour, Blowfish, CAST5, DES, AES, Twofish, Serpent, rfc2268 (rc2), SEED,
 Poly1305, Camellia, ChaCha20, IDEA, Salsa, SM4, Blake-2, CRC, MD2, MD4, MD5,
 RIPE-MD160, SM3, SHA-1, SHA-256, SHA-512, SHA3-224, SHA3-256, SHA3-384,
 SHA3-512, SHAKE128, SHAKE256, Tiger, Whirlpool, DSA, DSA2, ElGamal, RSA, ECC
 (Curve25519, sec256k1, GOST R 34.10-2001 and GOST R 34.10-2012, etc.)
 .
 This is a Windows version of libgcrypt. It's meant to be used when
 cross-building software that targets the Windows platform, e.g. the
 win32-loader component of Debian-Installer.
