Method Details

encode

public static char[] encode(byte[] p_aby)

Base64-encode a byte array.

Parameters:

p_aby - The array to encode.

Returns:

The encoded data as a character array.

encode

public static char[] encode(byte[] p_aby,
 int p_iOffset,
 int p_iLength)

Base64-encode a byte array with a specified offset and length.

Parameters:

p_aby - The array to encode.

p_iOffset - The offset where encoding begins.

p_iLength - Length to encode.

Returns:

The encoded data as a character array or null if p_aby is null or if p_iLength is 0.

decode

public static byte[] decode(char[] p_achSrc)

Decode a Base64-encoded byte array.

Parameters:

p_achSrc - Encoded byte array.

Returns:

The decoded byte array or null if p_achSrc is null or has zero length.

decode

public static byte[] decode(char[] p_achSrc,
 int p_iSrcLen)

Decode a Base64-encoded byte array.

Parameters:

p_achSrc - Encoded byte array.

p_iSrcLen - Length of the given byte array.

Returns:

The decoded byte array or null if p_achSrc is null or has zero length.
