Rust SHA2

Rust SHA2 is a Rust language implementation of the SHA-256 and SHA-512 hashing algorithms. These algorithms are commonly used to ensure the integrity and confidentiality of data.

Installation

To use Rust SHA2 in your Rust project, you can simply add it to your Cargo.toml file:

[dependencies]
sha2 = "0.9.5"

Usage

Once you've added SHA2 to your project, you can start hashing data. Here's an example of how to hash a string using SHA-256:

use sha2::{Sha256, Digest};

fn main() {
    let mut hasher = Sha256::new();
    hasher.update(b"hello world");
    let result = hasher.finalize();
    println!("{:x}", result);
}

This will output the SHA-256 hash of the string "hello world" in hexadecimal format.

You can also use SHA-512 by replacing Sha256 with Sha512 in the example above.

Conclusion

Using Rust SHA2, you can easily add SHA-256 and SHA-512 hashing functionality to your Rust projects. This can be helpful in ensuring the integrity and confidentiality of data in various applications.
