Examples of org.bouncycastle.crypto.DataLengthException

org.bouncycastle.crypto.DataLengthException
this exception is thrown if a buffer that is meant to have output copied into it turns out to be too short, or if we've been given insufficient input. In general this exception will get thrown rather than an ArrayOutOfBounds exception.
