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.', changed pages to 5, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2017-12-05, changed IESG state to RFC Published, created updates relation between draft-ietf-curdle-ssh-dh-group-exchange and RFC 4419) |
