Get the key transport encryption algorithm URI for the specified JCA key algorithm name, optional key
length and optional JCA key algorithm name of the key to be encrypted.
Note that typically the key length parameter is required for lookup of symmetric key wrap algorithm
URI's, but is typically not required or relevant for asymmetric key transport algorithms.
If a mapping is not available considering the optional key length and wrapped algorithm parameters as passed,
a lookup will next be attempted by omiting the (non-null) wrapped key algorithm, and if that is unsuccessful,
by then omitting the (non-null) key length parameter. If a mapping has still not been found, then a final
lookup attempt will be made using the key encryption key's JCA algorithm name alone.
