ECB — AES electronic codebook mode encryption

WebA block cipher works on units of a fixed size (known as a block size), but messages come in a variety of lengths.So some modes (namely ECB and CBC) require that the final block be padded before encryption.Several padding schemes exist.

"WebA message that is encrypted using the ECB mode should be extended until a size that is equal to an integer multiple of the single block length. A popular method of aligning the length of the last block is about appending an additional bit equal to 1 and then filling the rest of the block with bits equal to 0 . " - How does aes ecb work
