ft_ssl_md5 (subject)
You will recode part of the OpenSSL program, specifically the MD5 Hashing Algorithm.
This is the first ft_ssl project on the path of Encryption and Security. You will recode some security technologies you may have already been using, from scratch. You will want to plan out the structure of your executable before you begin, because you will build directly onto it in later security projects. It is of vital importance that your functions are modular, your code is easy to re-use and adding onto the executable doesn’t require rewriting the program. Re-read that last sentence again. I’m serious, do it. This project will focus specifically on cryptographic hashing algorithms to solidify your understanding of bitwise operations, integer overflow, and one-way functions. A subplot to this project is to emphasize writing clean code that can be efficiently extended.
git clone https://github.com/ChokMania/ft_ssl_md5.gitcd ft_ssl_md5; make
Usage: ./ft_ssl [Message Digest commands] [flags] [file]
Message Digest commands:
md5 sha224 sha256 sha384 sha512
Flags:
[-pqrlv] [-s string]
sh test/test.shThis will show you :
------------------------------------------ | 1.md5 2.sha224 3.sha256 4.sha384 | | 5.sha512 6.all 0.Exit . | ------------------------------------------
Simply choose one of the options to launch the test.
./ft_ssl md5 -s TestThis will convert the string "Test" in md5
