Constructor Detail

DERPrintableString

public DERPrintableString(byte[] string)
basic constructor - byte encoded string.


DERPrintableString

public DERPrintableString(String string)
basic constructor - this does not validate the string


DERPrintableString

public DERPrintableString(String string,
                          boolean validate)
Constructor with optional validation.

Parameters:
string - the base string to wrap.
validate - whether or not to check the string.
Throws:
IllegalArgumentException - if validate is true and the string contains characters that should not be in a PrintableString.
Method Detail

getInstance

public static DERPrintableString getInstance(Object obj)
return a printable string from the passed in object.

Throws:
IllegalArgumentException - if the object cannot be converted.

getInstance

return a Printable 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.
