SHA256 Hash the Bytes Represented in a Hex String

Demonstrates how to compute the SHA256 hash of the bytes represented by a hexidecimal encoded string, and return the hash bytes as an hex encoded string. Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// We wish to compute the SHA256 hash of the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...
let src = "6CF8EA51E4E0F599CF03EC8D58C3DCBC9C889A77FB2816B40DE25C2EC54E98A67EA517B".to_string();

let bd = chilkat::BinData::new();
let _ = bd.append_encoded(&src, "hex").is_ok();

// The bd now contains the bytes 0x6C 0xF8 0xEA 0x51 0xE4 0xE0 0xF5 0x99 0xCF ...

let crypt = chilkat::Crypt2::new();
crypt.set_hash_algorithm("sha256");
crypt.set_encoding_mode("hex");

// Hash the bytes contained in bd, and return the 32-byte SHA256 hash as a hexidecimal encoded string.
let result = crypt.hash_bd_enc(&bd).unwrap_or_default();
println!("{}", result);
