  "abstract": "The Diffie-Hellman (DH) Group Exchange for the Secure Shell (SSH) transport-layer protocol specifies that servers and clients should support groups with a minimum modulus group size of 1024 bits.  Recent security research has shown that the minimum value of 1024 bits is insufficient to protect against state-sponsored actors and any organization with enough computing resources.  This RFC updates RFC 4419, which allowed for DH moduli less than 2048 bits; now, 2048 bits is the minimum acceptable group size.",
