They're the same for CFB, OFB, and CTR modes. The other two, ECB and CBC,
can encrypt only whole blocks, or requires padding (which can be done for
you by StreamTransformationFilter). Padding will make the ciphertext longer.

Subject: Are the CipherText and PlainText always the same length?
Hello,
I`d like to know, after encrypting PlainText in any of BlockCipher/in
any of mode, are CipherText and PlainText always same length? Or are
there some modes or ciphers, which produce CipherText, that is longer/
shorter that PlainText?
