Trait sha2::Digest [] [src]

pub trait Digest: Input + BlockInput + FixedOutput + Default {
    fn new() -> Self { ... }
    fn input(&mut self, input: &[u8]) { ... }
    fn result(self) -> GenericArray<u8, Self::OutputSize> { ... }
    fn digest(data: &[u8]) -> GenericArray<u8, Self::OutputSize> { ... }
    fn digest_str(str: &str) -> GenericArray<u8, Self::OutputSize> { ... }

The Digest trait specifies an interface common to digest functions. It's a convinience wrapper around Input, FixedOutput, BlockInput and Default traits. It also provides additional convinience methods.

Provided Methods

Create new hasher instance

Digest input data. This method can be called repeatedly for use with streaming messages.

Retrieve the digest result. This method consumes digest instance.

Convinience function to compute hash of the data. It will handle hasher creation, data feeding and finalization.


println!("{:x}", sha2::Sha256::digest(b"Hello world"));

Convinience function to compute hash of the string. It's equivalent to digest(input_string.as_bytes()).
