==== Introduction ====

  : //This document provides recommendations for the implementation of
    public-key [[dido:public:ra:xapend:xapend.a_glossary:c:cryptography|cryptography]] based on the RSA algorithm
((R. Rivest, A. Shamir and L. Adleman.  A Method for Obtaining
Digital Signatures and Public-Key Cryptosystems.
Communications of the ACM, 21 (2), pp. 120-126, February 1978.
)), covering the
    following aspects://
    * //Cryptographic primitives//
    * //Encryption schemes//
    * //Signature schemes with appendix//
    * //ASN.1 [[dido:public:ra:xapend:xapend.a_glossary:s:syntax|syntax]] for representing [[dido:public:ra:xapend:xapend.a_glossary:k:key|keys]] and for identifying the schemes//

  : //The recommendations are intended for general application within
   computer and communications systems, and as such include a fair
   amount of flexibility.  It is expected that [[dido:public:ra:xapend:xapend.a_glossary:a:application|application]] standards
   based on these specifications may include additional constraints.
   The recommendations are intended to be compatible with the standard
   IEEE-1363-2000 [26] and draft standards currently being developed by
   the ANSI X9F1 [1] and IEEE P1363 [27] working groups.//
