As said in the heading, I want to know how the security of different padding methods, e.g. ANSI X.923, ISO 10126 and PKCS7, is compared to other methods to reach the needed block size, like ciphertext stealing or residual block termination. And what is about the counter mode of operation?
I heard that oracle attacks are possible if padding was applied, but have the other methods also disadvantages (except a higher complexity)? Or are there any possible ways for the problem that I forgot, that are more recommended?
