I'm trying to implement a diffie-hellman key exchange. Let's say I found a large prime number p - how can I find a generator g? Restricted by the multiprecision library that I have to use, only a few basic operations (+,., -, /, pow, modExp, modMult, mod, gcd, isPrime, genRandomPrime, genRandomBits, and a few more) are available. Dec 17, 2015  Unfortunately, Microsoft has chosen to use weak Diffie-Hellman key exchange parameters in order to support older Java clients. The only workaround for this that I know of is to disable all Diffie-Hellman cipher suites, leaving Elliptic Curve Diffie-Hellman to take care of forward secrecy, which is something you should really be doing anyway.

Future versions of OpenJDK may allow Diffie-Hellman parameters larger than 1024 bits. Services and protocols that have hard-coded Diffie-Hellman parameters may be updated to either generate or negotiate parameters or allow specifying parameters at runtime. Ubuntu's Response. The response to Logjam in Ubuntu is under review. I have upgraded 2 computer with Ubuntu 14.04LTS to 16.04LTS and I have a problem with openssh. With software like Putty 0.64 and less for example I can't establiseh a conexion with diffie-hellman-group-exchange-sha256 or diffie-hellman-group-exchange-sha1. The first working is diffie-hellman-group14-sha1.

There is no computationally feasible surefire way to go from a known modulus and private exponent to the corresponding public exponent.However:. Practical private key formats nearly always store more than n and d. Multiply the two primes together to produce the modulus (n). Do some math with the primes and the public exponent to produce the private exponent (d).The public key consists of the modulus and the public exponent.A minimal private key would consist of the modulus and the private exponent. Pick a public exponent (e). Generate public key mac -----begin-public-key---.

I have created an Ubuntu droplet (via Laravel Forge if that matters) and am trying to remote connect to MySql using Navicat. I have installes by SSH key and am able to connect via SSH. I am also able to log into MySql on the server once I am logged in.
