It checks that B<p> and B<q> are 16in fact prime, and that B<n = p*q>. 17 18It also checks that B<d*e = 1 mod (p-1*q-1)>, 19and that B<dmp1>, B<dmq1> and B<iqmp> are set correctly or are B<NULL>. 20 | 1=pod 2 3=head1 NAME 4 5RSA_check_key - validate private RSA keys 6 7=head1 SYNOPSIS 8 --- 4 unchanged lines hidden (view full) --- 13=head1 DESCRIPTION 14 15This function validates RSA keys.

| 21The key's public components may not be B<NULL>. | 21As such, this function can not be used with any arbitrary RSA key object, 22even if it is otherwise fit for regular RSA operation. See B<NOTES> for more 23information. |
| 22 23=head1 RETURN VALUE 24 25RSA_check_key() returns 1 if B<rsa> is a valid RSA key, and 0 otherwise. 26-1 is returned if an error occurs while checking the key. 27 28If the key is invalid or an error occurred, the reason code can be 29obtained using L<ERR_get_error(3)|ERR_get_error(3)>. 30 | 24 25=head1 RETURN VALUE 26 27RSA_check_key() returns 1 if B<rsa> is a valid RSA key, and 0 otherwise. 28-1 is returned if an error occurs while checking the key. 29 30If the key is invalid or an error occurred, the reason code can be 31obtained using L<ERR_get_error(3)|ERR_get_error(3)>. 32 |
| 33=head1 NOTES 34 35This function does not work on RSA public keys that have only the modulus 36and public exponent elements populated. It performs integrity checks on all 37the RSA key material, so the RSA key structure must contain all the private 38key data too. 39 |
