impl Hash
[src]
Utilities using the byteorder
crate.

pub fn from_low_u64_be(val: u64) -> Self
[src]
Creates a new hash type from the given u64
value.
Note
- The given
u64
value is interpreted as big endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
pub fn from_low_u64_le(val: u64) -> Self
[src]

value.
Note
- The given
u64
value is interpreted as little endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
pub fn from_low_u64_ne(val: u64) -> Self
[src]
Creates a new hash type from the given u64
value.
Note
- The given
u64
value is interpreted as native endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
impl Hash

crate.

given random number generator.

[src]
Assign self
to a cryptographically random value.
pub fn random_using<R: ?Sized>(rng: &mut R) -> Self where
R: Rng,

impl Hash
[src]
pub fn null_hash() -> Hash
[src]
Create a null hash with all zeros
pub fn hash(input: &[u8]) -> Hash
[src]
Hash a stream of bytes with Keccak 256
pub fn to_bytes(&self) -> [u8; 32]
[src]
Return the hash value
pub fn as_scalar(&self) -> PrivateKey
[src]
Return the scalar of the hash as a little endian number modulo l (curve order)
pub fn hash_to_scalar(input: &[u8]) -> PrivateKey
[src]
Hash a stream of bytes and return its scalar representation
The hash function H is the same Keccak function that is used in CryptoNote. When the value of the hash function is interpreted as a scalar, it is converted into a little-endian integer and taken modulo l.
