/* This test verifies padding with leading zeroes for shared

* In FIPS mode OPENSSL_DH_FIPS_MIN_MODULUS_BITS = 1024, meaning we need
* a FIPS-friendly >= 1024 bit prime, we can use MODP 14 from RFC 3526:
* https://www.ietf.org/rfc/rfc3526.txt
*
* We can generate appropriate values with this code:
*
* crypto = require('crypto');
*
* for (;;) {
* var a = crypto.getDiffieHellman('modp14'),
* var b = crypto.getDiffieHellman('modp14');
*
* a.generateKeys();
* b.generateKeys();
*
* var aSecret = a.computeSecret(b.getPublicKey()).toString('hex');
* console.log("A public: " + a.getPublicKey().toString('hex'));
* console.log("A private: " + a.getPrivateKey().toString('hex'));
* console.log("B public: " + b.getPublicKey().toString('hex'));
