Dear Rob III,

We understand your desire to move away from DH to your preferred key exchange algorithm: curve25519. We commit to posting notification to this forum should this algorithm be implemented in SecureCRT.

Note that as of SecureCRT 8.0, the DH exchange methods default to using primes that are at least 2048 bits, and you can increase this to even larger values as desired.
You would need to be connecting to a server that has a primes set that supports larger values in order to be successful, but you might very well be able to put to rest your concerns about 1024-bit primes with DH in the mean time by forcing 2048 or greater primes to be used during key exchange with an SSH2 server.
