Function sodiumoxide::crypto::stream::xsalsa20::stream_xor_ic

pub fn stream_xor_ic(m: &[u8], n: &Nonce, ic: u64, k: &Key) -> Vec<u8>

stream_xor_ic() encrypts a message m using a secret key k and a nonce n, it is similar to stream_xor() but allows the caller to set the value of the initial block counter ic.

stream_xor() guarantees that the ciphertext has the same length as the plaintext, and is the plaintext xor the output of stream(). Consequently stream_xor() can also be used to decrypt.
