Generates the shared secret, and places it into the buffer
sharedSecret
, beginning at offset
inclusive.
If the sharedSecret
buffer is too small to hold the
result, a ShortBufferException
is thrown.
In this case, this call should be repeated with a larger output buffer.
This method resets this KeyAgreementSpi
object,
so that it
can be reused for further key agreements. Unless this key agreement is
reinitialized with one of the engineInit
methods, the same
private information and algorithm parameters will be used for
subsequent key agreements.
