海外TECH	DEV Community	Learn Rust by implementing a SHA-1 hash cracker	https://dev.to/sylvainkerkour/learn-rust-by-implementing-a-sha-1-hash-cracker-3ip1	Learn Rust by implementing a SHA hash crackerOriginally published on my blog The moment has come to get your hands dirty let s write your first Rust program As for all the code examples in this course you can find the complete code in the accompanying Git repository cargo new sha crackerWill create a new project in the folder sha cracker Note that by default cargo will create a binary application project You can create a library project with the lib flag cargo new my lib lib SHA is a hash function used by a lot of old websites to store the passwords of the users In theory a hashed password can t be recovered from its hash Thus by storing the hash in their database a website can assert that a given user has the knowledge of its password without storing the password in cleartext by comparing the hashes So if the website s database is breached there is no way to recover the passwords and access the users data Reality is quite different Let s imagine a scenario where we just breached such a website and we now want to recover the credentials of the users in order to gain access to their accounts This is where a hash cracker is useful A hash cracker is a program that will try many different hashes in order to find the original password This is why when creating a website you should use a hash function specifically designed for this use case such as argonid which require way more resource to bruteforce than SHA for example This simple program will help us learn Rust s fundamentals How to use Command Line Interface CLI argumentsHow to read filesHow to use an external libraryBasic error handlingResources managementThis post is an excerpt from my book Black Hat RustLike in almost all programming languages the entrypoint of a Rust program is its main function ch sha cracker src main rsfn main Reading command line arguments is as easy as ch sha cracker src main rsuse std env fn main let args Vec lt String gt env args collect Where std env imports the module env from the standard library and env args calls the args function from this module and returns an iterator which can be collected into a Vec lt String gt a Vector of String objects A Vector is an array type that can be resized It is then easy to check for the number of arguments and display an error message if it does not match what is expected ch sha cracker src main rsuse std env fn main let args Vec lt String gt env args collect if args len println Usage println sha cracker lt wordlist txt gt lt sha hash gt return As you may have noticed the syntax of println with an exclamation mark is strange Indeed println is not a classic function but a macro As it s a complex topic I redirect you to the dedicated chapter of the Book println is a macro and not a function because Rust doesn t support yet variadic generics It has the advantage of being compile time evaluated and checked and thus prevent vulnerabilities such as format string vulnerabilities Error handlingHow should our program behave when encountering an error And how to inform the user of it This is what we call error handling Among the dozen programming languages that I have experience with Rust is without any doubts my favorite one regarding error handling due to its explicitness safety and conciseness For our simple program we will Box errors we will allow our program to return any type that implements the std error Error trait What is a trait More on that later ch sha cracker src main rsuse std env error Error const SHA HEX STRING LENGTH usize fn main gt Result lt Box lt dyn Error gt gt let args Vec lt String gt env args collect if args len println Usage println sha cracker lt wordlist txt gt lt sha hash gt return Ok let hash to crack args trim if hash to crack len SHA HEX STRING LENGTH return Err sha hash is not valid into Ok Reading filesAs it takes too much time to test all possible combinations of letters numbers and special characters we need to reduce the number of SHA hashes generated For that we use a special kind of dictionary known as a wordlist which contains the most common password found in breached websites Reading a file in Rust can be achieved with the standard library like that ch sha cracker src main rsuse std env error Error fs File io BufRead BufReader const SHA HEX STRING LENGTH usize fn main gt Result lt Box lt dyn Error gt gt let args Vec lt String gt env args collect if args len println Usage println sha cracker lt wordlist txt gt lt sha hash gt return Ok let hash to crack args trim if hash to crack len SHA HEX STRING LENGTH return Err sha hash is not valid into let wordlist file File open amp args let reader BufReader new amp wordlist file for line in reader lines let line line trim to string println line Ok CratesNow that the basic structure of our program is in place we need to actually compute the SHA hashes Fortunately for us some talented developers have already developed this complex piece of code and shared it online ready to use in the form of an external library In Rust we call those libraries or packages crates They can be browsed online at They are managed with cargo Rust s package manager Before using a crate in our program we need to declare its version in Cargo s manifest file Cargo toml ch sha cracker Cargo toml package name sha cracker version authors Sylvain Kerkour See more keys and their definitions at dependencies sha hex We can then import it in our SHA cracker ch sha cracker src main rsuse sha Digest use std env error Error fs File io BufRead BufReader const SHA HEX STRING LENGTH usize fn main gt Result lt Box lt dyn Error gt gt let args Vec lt String gt env args collect if args len println Usage println sha cracker lt wordlist txt gt lt sha hash gt return Ok let hash to crack args trim if hash to crack len SHA HEX STRING LENGTH return Err sha hash is not valid into let wordlist file File open amp args let reader BufReader new amp wordlist file for line in reader lines let line line let common password line trim if hash to crack amp hex encode sha Sha digest common password as bytes println Password found amp common password return Ok println password not found in wordlist Ok Hourray Our first program is now complete We can test it by running cargo run wordlist txt cacefbbbbcbcedcbPlease note that in a real world scenario we may want to use optimized hash crackers such as hashcat or John the Ripper which among other things may use the GPU to significantly speed up the cracking Another point would be to first load the wordlist in memory before performing the computations This post is an excerpt from my book Black Hat Rust RAIIA detail may have caught the attention of the most meticulous of you we opened the wordlist file but we never closed it This pattern or feature is called RAII Resource Acquisition Is Initialization In Rust variables not only represent parts of the memory of the computer they may also own resources Whenever an object goes out of scope its destructor is called and the owned resources are freed Thus you don t need to call a close method on files or sockets When the variable is dropped goes out of scope the file or socket will be automagically closed In our case the wordlist file variable owns the file and has the main function as scope Whenever the main function exits either due to an error or an early return the owned file is closed Magic isn t it Thanks to this it s very rare to leak resources in Rust Ok You might also have noticed that the last line of our main function does not contain the return keyword This is because Rust is an expression oriented language Expressions evaluate to a value Their opposites statements are instructions that do something and end with a semicolon So if our program reaches the last line of the main function the main function will evaluate to Ok which means success everything went according to the plan An equivalent would have been return Ok but not Ok Because here Ok is a statement due to the semicolon and the main function no longer evaluates to its expected return type Result Want to learn more about Rust applied cryptography and offensive security Take a look at my book Black Hat Rust	2022-09-26
