override void  Write (byte[] b, int off, int len)
  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.

Constructor & Destructor Documentation

◆ OutputStreamAesEncryption() [1/2]

iText.Kernel.Crypto.OutputStreamAesEncryption.OutputStreamAesEncryption ( Stream @  out,
byte[]  key,
int  off,
int  len 
)
inline

Creates a new instance of OutputStreamAesEncryption

Parameters
out the System.IO.Stream instance to be used as the destination for the encrypted content
key the byte array containing the key for encryption
off offset of the key in the byte array
len the length of the key in the byte array

◆ OutputStreamAesEncryption() [2/2]

iText.Kernel.Crypto.OutputStreamAesEncryption.OutputStreamAesEncryption ( Stream @  out,
byte[]  key 
)
inline

Creates a new instance of OutputStreamAesEncryption

Parameters
out the System.IO.Stream instance to be used as the destination for the encrypted content
key the byte array which is the key for encryption

Member Function Documentation

◆ Write()

override void iText.Kernel.Crypto.OutputStreamAesEncryption.Write ( byte[]  b,
int  off,
int  len 
)
inlinevirtual

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.

The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.

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
b the data.
off the start offset in the data.
len the number of bytes to write.
Exceptions
System.IO.IOException if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
