Function sodiumoxide::crypto::stream::chacha20::stream_xor_ic_inplace

pub fn stream_xor_ic_inplace(m: &mut [u8], Nonce: &Nonce, ic: u64, Key: &Key)

stream_xor_ic_inplace() encrypts a message m using a secret key k and a nonce n, it is similar to stream_xor_inplace() but allows the caller to set the value of the initial block counter ic. The stream_xor_ic_inplace() function encrypts the message in place.

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