- Constructor Detail
  - ByteArrayStream
```
public ByteArrayStream()
```
    Creates a new byte array output stream.
  - ByteArrayStream
```
public ByteArrayStream(int size)
```
    Creates a new byte array output stream with the specified size.
    Parameters:
    size - the initial size of the internal buffer
- Method Detail
  - asInputStream
```
public ByteArrayInputStream asInputStream()
```
    Creates an input stream from the written data. All data previously written. Zero-copy. Not a Pipe. Data written after this call will not appear.
    Returns:
    an input stream containing the written data
  - copyTo
```
public void copyTo(byte[] target,
                   int offset)
```
    Copies all written data to the target array.
    Parameters:
    target - the target
    offset - the offset in the target array
  - reset
```
public void reset()
```
    Resets this stream to the beginning.
    Overrides:
    reset in class ByteArrayOutputStream
    Throws:
    IllegalStateException - if previously written
  - sign
```
public Signature sign(I2PAppContext ctx,
                      SigningPrivateKey signingKey)
```
    Signs the written data.
    Parameters:
    ctx - the application context
    signingKey - the private key to sign with
    Returns:
    the signature, or null on error
  - sign
```
public Signature sign(SigningPrivateKey signingKey)
```
    Signs the written data.
    Parameters:
    signingKey - the private key to sign with
    Returns:
    the signature, or null on error
  - toByteArray
```
public byte[] toByteArray()
```
    Returns the byte array containing the written data. Zero-copy only if the data fills the buffer. Use asInputStream() for guaranteed zero-copy.
    Overrides:
    toByteArray in class ByteArrayOutputStream
    Returns:
    the byte array containing the written data
  - verifySignature
```
public boolean verifySignature(I2PAppContext ctx,
                               Signature signature,
                               SigningPublicKey verifyingKey)
```
    Verifies the signature of the written data.
    Parameters:
    ctx - the application context
    signature - the signature to verify
    verifyingKey - the public key to verify with
    Returns:
    true if the signature is valid
  - verifySignature
```
public boolean verifySignature(Signature signature,
                               SigningPublicKey verifyingKey)
```
    Verifies the signature of the written data.
    Parameters:
    signature - the signature to verify
    verifyingKey - the public key to verify with
    Returns:
    true if the signature is valid
