Crate hashjunkie 

Fast multi-algorithm hashing for files, streams, and byte slices.

HashJunkie computes many standard, cloud, and file-sharing hashes in one streaming pass. The high-level helpers are usually the right API for Rust applications:

use hashjunkie::{Algorithm, hash_bytes};

let result = hash_bytes(b"hello", &[Algorithm::Blake3, Algorithm::Sha256]);
assert_eq!(
    result.standard(Algorithm::Sha256),
    Some("2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824")
);

For files and arbitrary std::io::Read sources, use hash_file or hash_reader. These helpers use the same pipelined multi-hash engine as the CLI when several algorithms are requested.

use hashjunkie::{Algorithm, hash_reader};

let reader = Cursor::new(b"hello");
let result = hash_reader(reader, &[Algorithm::CidV1, Algorithm::Blake3])?;
assert!(result.standard(Algorithm::CidV1).unwrap().starts_with("bafk"));
