[−][src]Function tox_crypto::encrypt_precompute
pub fn encrypt_precompute(
their_public_key: &PublicKey,
our_secret_key: &SecretKey
) -> PrecomputedKey
Precomputes the shared key from their_public_key
and our_secret_key
.
For fast encrypt/decrypt - this way we can avoid an expensive elliptic curve scalar multiply for each encrypt/decrypt operation.
Use if communication is not one-time.
encrypt_precompute
does the shared-key generation once, so that it does
not have to be performed on every encrypt/decrypt.
This a wrapper for the
precompute()
function from sodiumoxide
crate.
