|

* Generic forms of RSA keys, public and private forms.
|
||
|
|
* All fields are in raw, unformatted binary format, as a byte pointer
|
||
|
|
* and a length, with the most significant byte first.
|
||
|
|
*
|
||
|
|
* The recip field in RSAPubKey is optional; it's the reciprocal of
|
||
|
|
* the modulus n. Providing this field is an optimization; if it's not
|
||
|
|
* provided, it will be calculated on the fly at some runtime cost. The
|
||
|
|
* recip field is not sensitive; it can be distributed and stored with
|
||
|
|
* no more security concern than the modulus itself. Providing the recip
|
||
|
|
* field yields approximately 28% speedup on public key operations.
|
||
|
|
*
|
||
|
|
* See libgRSAUtils/rsaKeyGen.[ch] or Tools/rsaKeyTool for info
|
||
|
|
* on obtaining the reciprocal.
