=head1 NAME

rsa_set0_all_params, rsa_get0_all_params
- Internal routines for getting and setting data in an RSA object

=head1 SYNOPSIS

 #include "crypto/rsa.h"

 int rsa_get0_all_params(RSA *r, STACK_OF(BIGNUM_const) *primes,
                         STACK_OF(BIGNUM_const) *exps,
                         STACK_OF(BIGNUM_const) *coeffs);
 int rsa_set0_all_params(RSA *r, const STACK_OF(BIGNUM) *primes,
                         const STACK_OF(BIGNUM) *exps,
                         const STACK_OF(BIGNUM) *coeffs);

=head1 DESCRIPTION

rsa_set0_all_params() sets all primes, CRT exponents and CRT coefficients
in the B<RSA> object I<r> to the contents of the stacks of BIGNUMs I<primes>,
I<exps> and I<coeffs>.  The B<RSA> object takes ownership of the BIGNUMs,
but not of the stacks.

rsa_get0_all_params() gets all primes, CRT exponents and CRT coefficients
in the B<RSA> object I<r> and pushes them on the stacks of constant BIGNUMs
I<primes>, I<exps> and I<coeffs>.  The B<RSA> object retains ownership of the
BIGNUMs, but not of the stacks.

=head1 NOTES

For RSA_set0_all_params() and RSA_get0_all_params():

=over 4

=item *

the I<primes> stack contains I<p>, I<q>, and then the rest of the primes
if the B<RSA> object is a multi-prime RSA key.

=item *

the I<exps> stack contains I<dP>, I<dQ>, and then the rest of the exponents
if the B<RSA> object is a multi-prime RSA key.

=item *

the I<coeffs> stack contains I<qInv>, and then the rest of the coefficients
if the B<RSA> object is a multi-prime RSA key.

=back

The number of primes must always be equal to the number of exponents, and
the number of coefficients must be one less than the number of primes.

=head1 RETURN VALUES

rsa_get0_all_params() and rsa_set0_all_params() return 1 on success, or
0 on failure.
