i have a source code for the aes ,but my key is 256bit,the plaintext must be 128bits,how i change the plaintext length,if my plaintext is 256bits,so i have to change the algorithm.how can i do???

This is not a good question - we cannot work out from that little what you are trying to do. Remember that we can't see your screen, access your HDD, or read your mind. Use the "Improve question" widget to edit your question and provide better information.

thank you ,because of my poor english,i have to do something in tiny platform ,so i need something small,code must be simple and fast,not really security

That's the one I am using: "256bit key - 128bit block - AES"[^]

Have you tried something yourself, except for crying "Help, Help!"? The source code in CPallini's link is not very bulky, so what do you mean by "something smaller"? If you think you can implement AES with much less code, then be invited to try.

The code I linked is pretty small. If you really need smaller code than you may also consider using another encryption method.
This is the one I would recommend:

It has asm optimization and is faster than anything else I found.
