# Method Nettle.BlockCipher16()->CCM.State()->digest()

Method digest

  `string(8bit) digest(int(4..16)|void bytes)`

Description

  Returns the CBC-MAC digest of the specified size.

Parameter `bytes`

  Size in bytes for the desired digest. Any even number in the range `[4..16]`. If not specified the value from calling digest_size() will be used.

Note

  Note that the digest length is folded into the digest, so it doesn't simply imply a truncation.
