The Digest trait specifies an interface common to digest functions, such as SHA-1 and the SHA-2 family of digest functions.

Required methods

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

Provide message data.

Arguments

• input - A vector of message data

fn result(&mut self, out: &mut [u8])

Retrieve the digest result. This method may be called multiple times.

Arguments

• out - the vector to hold the result. Must be large enough to contain output_bits().

fn reset(&mut self)

Reset the digest. This method must be called after result() and before supplying more data.

fn output_bits(&self) -> usize

Get the output size in bits.

fn block_size(&self) -> usize

Get the block size in bytes.

Provided methods

fn output_bytes(&self) -> usize

Get the output size in bytes.

fn input_str(&mut self, input: &str)

Convenience function that feeds a string into a digest.

Arguments

• input The string to feed into the digest

fn result_str(&mut self) -> String

Convenience function that retrieves the result of a digest as a String in hexadecimal format.

impl Digest for Ripemd160

fn reset(&mut self)

Resets the hash to its original state also clearing the buffer. To be used in between hashing separate messages to avoid having to recreate and allocate the whole structure.

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

Adds the input msg to the hash. This method can be called repeatedly for use with streaming messages.

fn result(&mut self, out: &mut [u8])

Returns the resulting digest of the entire message. Note: out must be at least 20 bytes (160 bits)

fn output_bits(&self) -> usize

Returns the size of the digest in bits

fn block_size(&self) -> usize

Returns the block size the hash operates on in bytes
