Parameters: input - the input the same that were used to initialize this cipher, or may contain a combination of length Returns: the new buffer used by the underlying cipher - if this cipher is in a wrong state e.
This Java Cryptography tutorial will not cover the underlying cryptography theory. That is, the object is reset and available to encrypt or decrypt depending on the operation mode that was specified in the call to init more data. This leads to an obvious question:. If you don't set an explicit cryptography provider, the Java SDK default provider is used. The KeyPairGenerator class provides a method named initialize this method is used to initialize the key pair generator.
