JSSE (which will not recognize them).

bufferStream
(package private) InputStream bufferStream
bytesOutstanding
(package private) int bytesOutstanding
pureSSL
(package private) boolean pureSSL
False if TLS packets are encapsulated in TDS packets.
readBuffer
(package private) final byte[] readBuffer
Temporary buffer used to de-encapsulate inital TLS packets.
Initial size should be enough for login phase after which no
buffering is required.
TdsTlsInputStream
public TdsTlsInputStream(InputStream in)
Constructs a TdsTlsInputStream and bases it on an underlying stream.
in
- the underlying stream
primeBuffer
private void primeBuffer()
throws IOException
Read in entire TLS record or TDS packet and store the TLS record in the
buffer. (TDS packets will always contain a TLS record.)
read
public int read(byte[] b,
int off,
int len)
throws IOException
readFully
private void readFully(byte[] b,
int off,
int len)
throws IOException
Reads len
bytes or throws an IOException
if
there aren't that many bytes available.
b
- buffer to read intooff
- offset in the buffer where to start storinglen
- amount of data to read
