Struct Hash

pub struct Hash {
    pub work_factor: WorkFactor,
    pub salt: Salt,
    pub hash: [u8; 23],
}

A bcrypt hash, comprising a work factor, salt, and digest bytes. Holds information equivalent to the $2b$… format created by OpenBSD’s bcrypt.

Fields

work_factor: WorkFactor

The hash’s work factor.

salt: Salt

The hash’s salt.

hash: [u8; 23]

The actual output of the hash.

Implementations

impl Hash

pub fn to_formatted(&self) -> [u8; 60]

Converts the hash to $2b$… form as exactly 60 ASCII bytes.

let hash = Hash {
    work_factor: WorkFactor::EXP4,
    salt: Salt::from_bytes(&[b'*'; 16]),
    hash: *b"\xa2\x16\x9di\xe4\x9c\xaa\xf5\xe6]0>\x81=_\\,N\xab\x0c\x00\xd3)",
};

assert_eq!(
    str::from_utf8(&hash.to_formatted()).unwrap(),
    "$2b$04$IgmoIgmoIgmoIgmoIgmoIemfYbYcQaotVkVR.8eRzdVAvMouu.ywi"
);

Trait Implementations

impl Clone for Hash

fn clone(&self) -> Hash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Hash

Parses a hash from the $2b$… format created by OpenBSD’s bcrypt. Also supports $2a$ and $2y$ prefixes from earlier and other implementations.

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.
