pub fn ctr_encrypt<C: BlockCipher>(cipher: &C, nonce: &[u8], data: &mut [u8])Expand description
Encrypt (or decrypt) data in CTR mode.
The nonce is used as the initial counter block. For a 128-bit cipher,
the nonce should typically be 12 bytes; the remaining 4 bytes are used as
a big-endian counter starting from 1. For shorter nonces, the counter
occupies the remaining bytes.
CTR mode is symmetric: encrypt and decrypt are the same operation.
