Constructor Detail

DERBitString

protected DERBitString(byte data, int padBits)

DERBitString

public DERBitString(byte[] data, int padBits)

Parameters: data the octets making up the bit string. padBits the number of extra bits at the end of the string.

DERBitString

public DERBitString(byte[] data)

DERBitString

public DERBitString(DEREncodable obj)

Method Detail

asn1Equals

protected boolean asn1Equals(DERObject o)

getBytes

protected static byte[] getBytes(int bitString)

return the correct number of bytes for a bit string defined in a 32 bit constant

getBytes

public byte[] getBytes()

getInstance

public static DERBitString getInstance(Object obj)

return a Bit String from the passed in object

Throws: IllegalArgumentException if the object cannot be converted.

getInstance

public static DERBitString getInstance(ASN1TaggedObject obj, boolean explicit)

return a Bit String from a tagged object.

Parameters: obj the tagged object holding the object we want explicit true if the object is meant to be explicitly tagged false otherwise.

Throws: IllegalArgumentException if the tagged object cannot be converted.
