This is a simple Rust program that calculates the SHA256 and MD5 hashes of a given file. The program uses multithreading to compute both hashes concurrently and outputs the result along with the count of each hash type.

the first code reads the file content, then spawns two threads to calculate the SHA256 and MD5 hashes. The results are stored in a shared hash map, which is then printed to the console.

The following external crates are used in this program:

crypto: Provides various cryptographic algorithms, including SHA256 and MD5.
console: Offers utility functions to interact with the terminal.

Add the following lines to your Cargo.toml file to include these dependencies:

[dependencies]
crypto = "0.2.36"
console = "0.15.5"

Compile the Rust code into an executable by running cargo build --release. This will generate a hasher.exe file in the target/release directory. Locate the hasher.exe file in the target/release directory. Drag and drop the file you want to hash onto the hasher.exe file. The application will open up in a command prompt or PowerShell window, showing the calculated hashes for the dragged file.

Compile the Rust code into an executable by running cargo build --release. This will generate a hasher.exe file in the target/release directory. Open a command prompt (CMD) or PowerShell window. Navigate to the directory containing the hasher.exe file using the cd command. Run the hasher application with the file path as an argument, like this: hasher.exe <file_location>. Replace <file_location> with the path to the file you want to hash.

For example, to grab a hash of the file named example.txt located in the same directory as hasher.exe, you would run the following command:

  hasher.exe example.txt

The application will then calculate the SHA256 and MD5 hashes of the specified file and display the results in the command prompt or PowerShell window.
