std.crypto.hash.Hash

class pub Hash

The output of a cryptographic or (cryptography related) universal hash function.

Unlike std.hash.Hash, this type is produced by hashers rather than a trait to implement. In addition it's aimed at hasher related to cryptography, such as SHA256 and Poly1305. This type isn't suitable for hashing arbitrary Inko types.

Fields

bytes

let pub @bytes: ByteArray

The bytes that make up this Hash.

Static methods

new

Show source code

fn pub static new(bytes: ByteArray) -> Hash {
  Hash(bytes)
}

fn pub static new(bytes: ByteArray) -> Hash

Returns a new empty Digest.

Instance methods

!=

Show source code

fn pub !=(other: T) -> Bool {
  (self == other).false?
}

fn pub !=(other: T) -> Bool

Returns true if self and the given object are not equal to each other.

==

Show source code

fn pub ==(other: ref Hash) -> Bool {
  @bytes == other.bytes
}

fn pub ==(other: ref Hash) -> Bool

Returns true if self and the given object are equal to each other.

This operator is used to perform structural equality. This means two objects residing in different memory locations may be considered equal, provided their structure is equal. For example, two different arrays may be considered to have structural equality if they contain the exact same values.

fmt

Show source code

fn pub fmt(formatter: mut Formatter) {
  formatter.write(to_string)
}

fn pub fmt(formatter: mut Formatter)

Formats self in a human-readable format for debugging purposes.

to_string

Show source code

fn pub to_string -> String {
  # We don't use Int.format here because we need extra padding, and to avoid
  # allocating a String for every byte.
  let hex = ByteArray.filled(with: 0, times: @bytes.size * 2)

  @bytes.iter.each_with_index(fn (index, byte) {
    let hex_index = index * 2

    hex.set(hex_index, HEX_DIGITS.byte(byte >> 4))
    hex.set(hex_index + 1, HEX_DIGITS.byte(byte & 0x0F))
  })

  hex.into_string
}

fn pub to_string -> String

Returns a hexadecimal String of this digest.
