Examples of PaddedBufferedBlockCipher

org.bouncycastle.crypto.paddings.PaddedBufferedBlockCipher
A wrapper class that allows block ciphers to be used to process data in a piecemeal fashion with padding. The PaddedBufferedBlockCipher outputs a block only when the buffer is full and more data is being added, or on a doFinal (unless the current block in the buffer is a pad block). The default padding mechanism used is the one outlined in PKCS5/PKCS7.
