Method Detail

containsOnlyBase64UrlChars

public static boolean containsOnlyBase64UrlChars(byte[] bytes,
                                                 int offset,
                                                 int len)

encodeToChar

public static char[] encodeToChar(byte[] sArr)

Encodes a raw byte array into a BASE64Url char[] representation i accordance with RFC 2045.

Parameters:

sArr - The bytes to convert. If null or length 0 an empty array will be returned.

Returns:

A BASE64Url encoded array. Never null.

decodeFast

public static byte[] decodeFast(char[] sArr)

Decodes a BASE64Url encoded char array that is known to be reasonably well formatted. The preconditions are:
+ The array must have no line separators at all (one line).
+ The array may not contain illegal characters within the encoded string
+ The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.

Parameters:

sArr - The source array. Length 0 will return an empty array. null will throw an exception.

Returns:

The decoded array of bytes. May be of length 0.

encodeToByte

public static byte[] encodeToByte(byte[] sArr)

Encodes a raw byte array into a BASE64Url byte[] representation i accordance with RFC 2045.

Parameters:

sArr - The bytes to convert. If null or length 0 an empty array will be returned.

Returns:

A BASE64Url encoded array. Never null.

decodeFast

public static byte[] decodeFast(byte[] sArr)

Decodes a BASE64Url encoded byte array that is known to be reasonably well formatted. The preconditions are:
+ The array must have no line separators at all (one line).
+ The array may not contain illegal characters within the encoded string
+ The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.

Parameters:

sArr - The source array. Length 0 will return an empty array. null will throw an exception.

Returns:

The decoded array of bytes. May be of length 0.

encodeToString

public static String encodeToString(byte[] sArr)

Encodes a raw byte array into a BASE64Url String representation i accordance with RFC 2045.

Parameters:

sArr - The bytes to convert. If null or length 0 an empty array will be returned.

Returns:

A BASE64Url encoded array. Never null.

decodeFast

public static byte[] decodeFast(String s)

Decodes a BASE64Url encoded string that is known to be resonably well formatted. The preconditions are:
+ The array must have no line separators at all (one line).
+ The array may not contain illegal characters within the encoded string
+ The array CAN have illegal characters at the beginning and end, those will be dealt with appropriately.

Parameters:

s - The source string. Length 0 will return an empty array. null will throw an exception.

Returns:

The decoded array of bytes. May be of length 0.
