Trait digest::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 for digest functions.

It's a convinience wrapper around Input, FixedOutput, BlockInput and Default traits. It also provides additional convinience methods.

Provided Methods

`fn new() -> Self`

Create new hasher instance

`fn input(&mut self, input: &[u8])`

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

`fn result(self) -> GenericArray<u8, Self::OutputSize>`

Retrieve the digest result. This method consumes digest instance.

`fn digest(data: &[u8]) -> GenericArray<u8, Self::OutputSize>`

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

Example:

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

`fn digest_str(str: &str) -> GenericArray<u8, Self::OutputSize>`

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