Struct ring::aead::SealingKey [−][src]
An AEAD key for encrypting and signing (“sealing”), bound to a nonce sequence.
Intentionally not Clone
or Copy
since cloning would allow duplication
of the nonce sequence.

impl<N: NonceSequence> SealingKey<N>
[src]
pub fn seal_in_place<A, InOut>(
&mut self,
aad: Aad<A>,
in_out: &mut InOut
) -> Result<(), Unspecified> where
A: AsRef<[u8]>,
InOut: AsMut<[u8]> + for<'in_out> Extend<&'in_out u8>,
[src]
&mut self,

) -> Result<(), Unspecified> where
A: AsRef<[u8]>,

Renamed to seal_in_place_append_tag

Deprecated. Renamed to seal_in_place_append_tag()

pub fn seal_in_place_append_tag<A, InOut>(
&mut self,
aad: Aad<A>,
in_out: &mut InOut
) -> Result<(), Unspecified> where
A: AsRef<[u8]>,
InOut: AsMut<[u8]> + for<'in_out> Extend<&'in_out u8>,
[src]
&mut self,
aad: Aad<A>,
in_out: &mut InOut
) -> Result<(), Unspecified> where
A: AsRef<[u8]>,
InOut: AsMut<[u8]> + for<'in_out> Extend<&'in_out u8>,
Encrypts and signs (“seals”) data in place, appending the tag to the resulting ciphertext.
key.seal_in_place_append_tag(aad, in_out)
is equivalent to:
key.seal_in_place_separate_tag(aad, in_out.as_mut())
.map(|tag| in_out.extend(tag.as_ref()))
pub fn seal_in_place_separate_tag<A>(
&mut self,
aad: Aad<A>,
in_out: &mut [u8]
) -> Result<Tag, Unspecified> where
A: AsRef<[u8]>,
[src]
&mut self,
aad: Aad<A>,
in_out: &mut [u8]
) -> Result<Tag, Unspecified> where
A: AsRef<[u8]>,
Encrypts and signs (“seals”) data in place.
aad
is the additional authenticated data (AAD), if any. This is
authenticated but not encrypted. The type A
could be a byte slice
&[u8]
, a byte array [u8; N]
for some constant N
, Vec<u8>
, etc.
If there is no AAD then use Aad::empty()
.
The plaintext is given as the input value of in_out
. seal_in_place()
will overwrite the plaintext with the ciphertext and return the tag.
For most protocols, the caller must append the tag to the ciphertext.
The tag will be self.algorithm.tag_len()
bytes long.
