Constructors

OutputStreamAesEncryption(Stream, byte[])

Creates a new instance of OutputStreamAesEncryption

public OutputStreamAesEncryption(Stream @out, byte[] key)

Parameters

out Stream

the Stream instance to be used as the destination for the encrypted content

key byte[]

the byte array which is the key for encryption

OutputStreamAesEncryption(Stream, byte[], int, int)

Creates a new instance of OutputStreamAesEncryption

public OutputStreamAesEncryption(Stream @out, byte[] key, int off, int len)

Parameters

out Stream

the Stream instance to be used as the destination for the encrypted content

key byte[]

the byte array containing the key for encryption

off int

offset of the key in the byte array

len int

the length of the key in the byte array

Fields

cipher

protected AESCipher cipher

Field Value

AESCipher

Methods

Finish()

public override void Finish()

Write(byte[], int, int)

Writes len bytes from the specified byte array starting at offset off to this output stream.

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

Parameters

b byte[]

the data.

off int

the start offset in the data.

len int

the number of bytes to write.

Remarks

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.
