Class AESCipherCBCnoPad

java.lang.Object
com.itextpdf.kernel.crypto.AESCipherCBCnoPad
@Deprecated public class AESCipherCBCnoPad extends Object
Deprecated.
the AES-CBC cipher is a low-level cryptographic primitive that requires careful understanding to use it safely. This class is only a thin wrapper and is not intended for general use. Instead, use API provided by cryptography libraries directly or rely on high-level PDF encryption functionality.
Creates an AES Cipher with CBC and no padding.
