Method Detail

base64

public static String base64(byte[] buf)

Base-64 encode a byte array, returning the returning string.

Note that this method exists merely to be compatible with the challenge-response authentication method of rsyncd. It is not technincally a Base-64 encoder.

Parameters:

buf - The byte array to encode.

Returns:

buf encoded in Base64.

writeASCII

public static void writeASCII(OutputStream out,
                              String ascii)
                       throws IOException

Write a String as a sequece of ASCII bytes.

Parameters:

out - The OutputStream to write to.

ascii - The ASCII string to write.

Throws:

IOException - If writing fails.

readLine

public static String readLine(InputStream in)
                       throws IOException

Read up to a '\n' or '\r', and return the resulting string. The input is assumed to be ISO-8859-1.

Parameters:

in - The InputStream to read from.

Returns:

The line read, without the line terminator.

Throws:

IOException

toHexString

public static String toHexString(byte[] b)

Convert a byte array to a big-endian ordered hexadecimal string.

Parameters:

b - The bytes to convert.

Returns:

A hexadecimal representation to b.

toHexString

public static String toHexString(byte[] b,
                                 int off,
                                 int len)

Convert a byte array to a big-endian ordered hexadecimal string.

Parameters:

b - The bytes to convert.

Returns:

A hexadecimal representation to b.
