public Base64Encoder()

Method Detail

encode

public static void encode(InputStream in,
                          OutputStream out)
                   throws IOException

Encodes data from supplied input to output.

Parameters:

in - The input stream to be encoded.

out - The output stream, to write encoded data to.

Throws:

IOException

encode

public static void encode(byte[] input,
                          OutputStream out)
                   throws IOException

Encode the supplied byte array and write the encoded data to the OutputStream out.

Throws:

IOException

encode

public static String encode(String input)
                     throws IOException

Encode the given string,and return the encoded version as a string.

Returns:

A String, representing the encoded content of the input String.

Throws:

IOException

encode

public static String encode(byte[] bytes)
                     throws IOException

Encode the given byte array and return the result as a string.

Throws:

IOException

main

public static void main(String[] args)
                 throws Exception

Run with one argument, prints the encoded version of it. With two, the second is assumed to be the name of a MessageDigest to be applied to the string before encoding (useful for generating password hashes).

Alternatively, use the openssl utility, for example:

echo -n "password" | openssl dgst -sha1 -binary | openssl base64

Throws:

Exception
