Method Detail

encode

public static final java.lang.String encode(byte[] src)

Encodes a byte array into Base64 notation. Equivalent to calling encode(source, 0, source.length).

Parameters:

src - the data to convert.

---

encode

public static final java.lang.String encode(byte[] src,
 int off,
 int len,
 boolean breakLines)

Encodes a byte array into Base64 notation.

Parameters:

src - the data to convert.

off - offset in array where conversion should begin.

len - length of data to convert.

breakLines - break lines at 80 characters or less.

---

decode

public static final byte[] decode(java.lang.String s)

Decodes data from Base64 notation.

Parameters:

s - the string to decode.

Returns:

the decoded data.

---

decode

public static byte[] decode(byte[] src,
 int off,
 int len)

Decodes Base64 content in byte array format and returns the decoded byte array.

Parameters:

src - the Base64 encoded data.

off - the offset of where to begin decoding.

len - the length of characters to decode.

Returns:

the decoded data.

Throws:

java.lang.IllegalArgumentException - if src contains an illegal Base-64 character.
