A builder for PGPDigestCalculatorProvider instances that obtain cryptographic primitives using the JCA API.

By default digest calculator providers obtained from this builder will use the default JCA algorithm lookup mechanisms (i.e. specifying no provider), but a specific provider can be specified prior to building.

public void write(byte[] bytes, int off, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Parameters
bytes:byte[]

the data.

off:int

the start offset in the data.

len:int

the number of bytes to write.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
writeback to summary
public void write(byte[] bytes) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes b.length bytes from the specified byte array to this output stream. The general contract for write(b) is that it should have exactly the same effect as the call write(b, 0, b.length).

Parameters
bytes:byte[]

the data.

Exceptions
IOException:
if an I/O error occurs.
writeback to summary
public void write(int b) throws IOException

Implements abstract java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Parameters
b:int

the byte.

Exceptions
IOException:
if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.
