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

public static DERPrintableString getInstance(ASN1TaggedObject obj,
                                             boolean explicit)

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.

getString

public String getString()

Specified by:

getString in interface DERString

getOctets

public byte[] getOctets()

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Object

toString

public String toString()

Overrides:

toString in class Object

isPrintableString

public static boolean isPrintableString(String str)

return true if the passed in String can be represented without loss as a PrintableString, false otherwise.

Returns:

true if in printable set, false otherwise.
