Encryption step 1) calculating the median N effective tn (in bytes) of the maximum zero-bit ignored, so that tn1 = tn-1. For example, N = 0x012A05, its effective median tn = 5, tn1 = 4. 2) to express the data A is separated into TN1 bit (in bytes) of the block, as a lump sum for each block, block number recorded as bn. Thus, to ensure that each block are less than N. 3) A 1 Ai for each Bi = Ai ^ E MOD N computing. Bi is a piece of ciphertext data of all ciphertext blocks combined together, we received ciphertext data B.
