public RSAPKCS1V1_5Signature()
Default 0-arguments constructor. Uses SHA-1 as the default hash.
public RSAPKCS1V1_5Signature(String mdName)
Constructs an instance of this object using the designated message digest algorithm as its underlying hash function.
- Parameters:
mdName
- the canonical name of the underlying hash function.
public Object clone()
This method may be called to create a new copy of the Object. The typical behavior is as follows:
o == o.clone()
is falseo.getClass() == o.clone().getClass()
is trueo.equals(o)
is trueHowever, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override
Object.equals(Object)
.If the Object you call clone() on does not implement
Cloneable
(which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.
All array types implement Cloneable, and override this method as follows (it should never fail):
public Object clone() { try { super.clone(); } catch (CloneNotSupportedException e) { throw new InternalError(e.getMessage()); } }
