What is Cygwin?
• Cygwin is a “free” Linux-like environment for Windows. It consists of two parts: – A DLL (cygwin1.dll) which acts as a Linux API A DLL (cygwin1.dll) which acts as a Linux API
emulation layer providing substantial Linux API functionality.
– A collection of tools which provide Linux look and feel.

Cygwin Installation (8/13)
Select packages to install (See next slide).By default, “setup.exe” will install only the packages in the Base category and their dependencies, resulting in a minimal Cygwin installation.
11
Minimal Cygwin installation will not include many commonly used tools such as gcc (which you will find in the Devel category).
Cygwin Installation (9/13)
So, the following packages at miminum must be selected to install “OpenSSL“ packages later on.
Category | Packages- editor : vim (other editors available)- devel : gcc-core ( gcc-mingw-core by default )- devel : gcc-core ( gcc-mingw-core, by default )
gcc-g++ ( gcc-mingw-g++, by default)make

What is OpenSSL?
• “Free” library providing cryptographic functions
• The important feature is the complete implementation of the protocols SSL and TLSthe protocols SSL and TLS

Algorithms implemented
• Block ciphers: DES, 3DES, DESX, CAST, RC2, RC5, IDEA, Blowfish
• stream cipher: RC4stream cipher RC4• hash: MD2, MD4, MD5, SHA-1, RIPEMD 160, MDC2• asymmetric cryptosystems: RSA, DSA, DH• MAC: HMAC
