Struct Sha1

pub struct Sha1 { /* private fields */ }

SHA-1 hash function

Implementations

impl Sha1

pub fn new() -> Self

Creates a new SHA-1 hasher

Trait Implementations

impl Clone for Sha1

fn clone(&self) -> Sha1

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Sha1

fn default() -> Self

Returns the “default value” for a type.

impl HashFunction for Sha1

type Algorithm = Sha1Algorithm

The algorithm type that defines constants and properties

type Output = Digest<SHA1_OUTPUT_SIZE>

The output digest type with size guarantees

fn new() -> Self

Creates a new instance of the hash function.

fn update(&mut self, data: &[u8]) -> Result<&mut Self>

Updates the hash state with data, returning self for chaining.

fn finalize(&mut self) -> Result<Self::Output>

Finalizes and returns the digest.

fn output_size() -> usize

The output size in bytes.

fn block_size() -> usize

The internal block size in bytes.

fn name() -> String

Human-readable name.

fn finalize_reset(&mut self) -> Result<Self::Output>

Finalizes, returns the digest, and resets state.

fn digest(data: &[u8]) -> Result<Self::Output>

Convenience: one-shot digest computation with fluent interface.

fn verify(data: &[u8], expected: &Self::Output) -> Result<bool>

where Self::Output: PartialEq,

Convenience method to verify a hash against input data

impl Zeroize for Sha1

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
