Members

Functions

doFinal uint doFinal(ubyte[] output): encrypt the remaining bytes in the buffer
getUnderlyingCipher Cipher getUnderlyingCipher()
processByte uint processByte(ubyte b, ubyte[] output): takes one byte and stores it in a buffer. Only if the buffer is full it gets encrypted and the cipher text gets written to output.
processBytes uint processBytes(ubyte[] i, ubyte[] output): encrypt or decrypt byte array
reset void reset(): Undocumented in source. Be warned that the author may not have intended to support it.
start void start(bool forEncryption, ubyte[] key, ubyte[] iv): Undocumented in source. Be warned that the author may not have intended to support it.

Manifest constants

blockSize enum blockSize;: Undocumented in source.
name enum name;: Undocumented in source.

Variables

buf ubyte[blockSize] buf;: buffer for incomplete blocks
bufOff uint bufOff;: where the next byte get added to the buffer (i.e. buf[bufOff++] = newByte)
cipher Cipher cipher;: the underlying block cipher

Parameters

permitPartialBlock: tells wether the underlying cipher supports a partial last block (CTR does). default: false

Examples

BufferedBlockCipher!AES) ecbEncryption; BufferedBlockCipher!(CTR!AES, true) ctrEncryption;
