Struct secure_serialisation::PrecomputedKey
[−]
[src]
#[must_use]pub struct PrecomputedKey(pub [u8; PRECOMPUTEDKEYBYTES]);
Applications that send several messages to the same receiver can gain speed by
splitting seal() into two steps, precompute() and seal_precomputed().
Similarly, applications that receive several messages from the same sender can gain
speed by splitting open() into two steps, precompute() and open_precomputed().
When a PrecomputedKey goes out of scope its contents will be zeroed out
Methods
impl PrecomputedKey[src]
fn from_slice(bs: &[u8]) -> Option<PrecomputedKey>[src]
from_slice() creates an object from a byte slice
This function will fail and return None if the length of
the byte-slice isn't equal to the length of the object
Trait Implementations
impl Index<RangeFrom<usize>> for PrecomputedKey[src]
Allows a user to access the byte contents of an object as a slice.
WARNING: it might be tempting to do comparisons on objects
by using x[a..] == y[a..]. This will open up for timing attacks
when comparing for example authenticator tags. Because of this only
use the comparison functions exposed by the rust_sodium API.
impl Index<RangeTo<usize>> for PrecomputedKey[src]
Allows a user to access the byte contents of an object as a slice.
WARNING: it might be tempting to do comparisons on objects
by using x[..b] == y[..b]. This will open up for timing attacks
when comparing for example authenticator tags. Because of this only
use the comparison functions exposed by the rust_sodium API.
impl Index<RangeFull> for PrecomputedKey[src]
Allows a user to access the byte contents of an object as a slice.
WARNING: it might be tempting to do comparisons on objects
by using x[] == y[]. This will open up for timing attacks
when comparing for example authenticator tags. Because of this only
use the comparison functions exposed by the rust_sodium API.
