Method Detail

encodeString

public static java.lang.String encodeString(java.lang.String s)

Encodes a string into Base64 format. No blanks or line breaks are inserted.

Parameters:

s - A String to be encoded.

Returns:

A String containing the Base64 encoded data.

encode

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

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:

in - An array containing the data bytes to be encoded.

Returns:

A character array containing the Base64 encoded data.

encode

public static char[] encode(byte[] in,
                            int iLen)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:

in - An array containing the data bytes to be encoded.

iLen - Number of bytes to process in in.

Returns:

A character array containing the Base64 encoded data.

encode

public static char[] encode(byte[] in,
                            int iOff,
                            int iLen)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:

in - An array containing the data bytes to be encoded.

iOff - Offset of the first byte in in to be processed.

iLen - Number of bytes to process in in, starting at iOff.

Returns:

A character array containing the Base64 encoded data.

decodeString

public static java.lang.String decodeString(java.lang.String s)

Decodes a string from Base64 format. No blanks or line breaks are allowed within the Base64 encoded input data.

Parameters:

s - A Base64 String to be decoded.

Returns:

A String containing the decoded data.

Throws:

java.lang.IllegalArgumentException - If the input is not valid Base64 encoded data.

decode

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

Decodes a byte array from Base64 format. No blanks or line breaks are allowed within the Base64 encoded input data.

Parameters:

s - A Base64 String to be decoded.

Returns:

An array containing the decoded data bytes.

Throws:

java.lang.IllegalArgumentException - If the input is not valid Base64 encoded data.

decode

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

Parameters:

in - A character array containing the Base64 encoded data.

Returns:

An array containing the decoded data bytes.

Throws:

java.lang.IllegalArgumentException - If the input is not valid Base64 encoded data.

decode

public static byte[] decode(char[] in,
                            int iOff,
                            int iLen)

Decodes a byte array from Base64 format. No blanks or line breaks are allowed within the Base64 encoded input data.

Parameters:

in - A character array containing the Base64 encoded data.

iOff - Offset of the first character in in to be processed.

iLen - Number of characters to process in in, starting at iOff.

Returns:

An array containing the decoded data bytes.

Throws:

java.lang.IllegalArgumentException - If the input is not valid Base64 encoded data.
