[−][src]Struct block_padding::NoPadding
Don't pad the data. Useful for key wrapping.
use block_padding::{NoPadding, Padding}; use generic_array::{GenericArray, typenum::U8}; let msg = b"test"; let pos = msg.len(); let mut block: GenericArray::<u8, U8> = [0xff; 8].into(); block[..pos].copy_from_slice(msg); NoPadding::pad(&mut block, pos); assert_eq!(&block[..], b"test\xff\xff\xff\xff"); let res = NoPadding::unpad(&block).unwrap(); assert_eq!(res, b"test\xff\xff\xff\xff");
Note that even though the passed length of the message is equal to 4,
the size of unpadded message is equal to the block size of 8 bytes.
Also padded message contains "garbage" bytes stored in the block buffer.
Thus NoPadding
generally should not be used with data length of which
is not multiple of block size.
