AES encryptAesCbc Error

[windy-itus]

encryptAesCbc func in AES occurs indexoutofboundsexception with "words" val has lengh = 5. Is this an error?

@bibinbodongti can you provide an example of usage that reproduces the problem?
Ideally if you can provide an assertEquals, that would be easier to add a test, fix it and prevent regressions

For Ex:
I have data=[0, 0, 4, 1, 0, 0, 0, 0, 0, 14, 0, 0, 0, 14, 0, 1, 4, 1, 1, 0] (Byte[20])
and key = [17, 9, 12, 81, -92, 44, 11, -104, -51, 43, 123, 116, -128, -40, 13, -56, 100, 88, 37, -116, 1, 12,
48, 110, 96, -23, 76, -34, 127, -114, -81, -5] (Byte[32])
I call command: AES.encryptEes128Cbc(data, key).
Then, I receive java.lang.arrayindexoutofboundsexception: length=5; index=5 encryptaes128cbc

Yeah it seems to be expected. But the error reported was a bit misleading. I have handled it here:

• soywiz-archive/korge-next@54f3207
• soywiz-archive/korge-next@bd4e867

If the number of bytes you are providing in the data are not multiple of 16, you have to specify a padding algorithm.

For example:

AES.encryptEes128Cbc(data, key, padding = Padding.PKCS7Padding)

Awesome. Thank you very much
