[AK] - its because API comments are ambiguous in this case and we have only one field describing array length.
I would suggest to rephrase cipher field API comments from "length in bytes
	 * of this field needs to be greater or equal to the length of
	 * corresponding RSA key in bytes"
To "underlying array should have allocated enough memory to hold cipher output (bigger or equal to RSA key size". Then length could and I think should be zero or unspecified at this point. 
What do you think?
