Method Detail

encode

public byte[] encode()

Encode this object into it's DER type.

Specified by:

encode in interface DEREncoder

Returns:

DER encoded object

decode

public static String decode(ByteBuffer encoded)

Converts bytes in the buffer to a string by reading from the current position to the limit, which assumes the bytes of the string are in big-endian order.

Parameters:

encoded - buffer containing DER-encoded data where the buffer is positioned at the start of string bytes and the limit is set beyond the last byte of string data.

Returns:

decoded bytes as an string

toBytes

public static byte[] toBytes(String s)

Converts the supplied string to a byte array using the UTF-8 encoding.

Parameters:

s - to convert

Returns:

byte array
