DERNumericString

public DERNumericString(byte[] string)

basic constructor - with bytes.

DERNumericString

public DERNumericString(java.lang.String string)

basic constructor - without validation..

DERNumericString

public DERNumericString(java.lang.String string,
                        boolean validate)

Constructor with optional validation.

Parameters:

string - the base string to wrap.

validate - whether or not to check the string.

Throws:

java.lang.IllegalArgumentException - if validate is true and the string contains characters that should not be in a NumericString.

Method Detail

getInstance

public static DERNumericString getInstance(java.lang.Object obj)

return a Numeric string from the passed in object

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getInstance

public static DERNumericString getInstance(ASN1TaggedObject obj,
                                           boolean explicit)

return an Numeric 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:

java.lang.IllegalArgumentException - if the tagged object cannot be converted.
