24 | - INCOMPATIBLE CHANGE: core protocol version 1.0. |
|
|
25 | - while individual packets couldn't be replayed, a whole session |
|
|
26 | could be replayed - this has been fixed by an extra key exchange. |
|
|
27 | - in addition to rsa key exchange and authentication, the handshake now |
|
|
28 | adds a diffie-hellman key exchange (using curve25119) for perfect |
|
|
29 | forward secrecy. mac and cipher keys are derived using HKDF. |
|
|
30 | - rsa key sizes are now configurable and larger (default is 3072). |
|
|
31 | correspondingly, the minimum mtu is no longer 296 but 576. |
|
|
32 | - fixed a potential (unverified) buffer overrun on rsa decryption. |
|
|
33 | - gvpectrl no longer generates all missing public keys, but |
|
|
34 | only missing private keys. private keys are also put |
|
|
35 | into the configured location. |
|
|
36 | - the pid-file now accepts %s as nodename as elsewhere. |
|
|
37 | - no longer use RAND_bytes to generate session keys - you NEED |
|
|
38 | a real source of entropy now (e.g. egd or /dev/random - see the |
|
|
39 | openssl documentation). |
