faa069a126 peer-level integration test for crypto handshake
- add const length params for handshake messages
- add length check to fail early
- add debug logs to help interop testing (!ABSOLUTELY SHOULD BE DELETED LATER)
- wrap connection read/writes in error check
- add cryptoReady channel in peer to signal when secure session setup is finished
- wait for cryptoReady or timeout in TestPeersHandshake

20aade56c3 chop first byte when cryptoid.PubKeyS is set from identity.Pubkey() since this is directly copied in the auth message 2015-02-06 00:00:35 +01:00

364b783281 changes that fix it all:
- set proper public key serialisation length in pubLen = 64
- reset all sizes and offsets
- rename from DER to S (we are not using DER encoding)
- add remoteInitRandomPubKey as return value to respondToHandshake
- add ImportPublicKey with error return to read both EC golang.elliptic style 65 byte encoding and 64 byte one
- add ExportPublicKey falling back to go-ethereum/crypto.FromECDSAPub() chopping off the first byte
- add Import - Export tests
- all tests pass

e252c634cb first stab at integrating crypto in our p2p
- abstract the entire handshake logic in cryptoId.Run() taking session-relevant parameters
- changes in peer to accomodate how the encryption layer would be switched on
- modify arguments of handshake components
- fixed test getting the wrong pubkey but it till crashes on DH in newSession()

714b955d6e fix crash
- add session token check and fallback to shared secret in responder call too
- use explicit length for the types of new messages
- fix typo resp[resLen-1] = tokenFlag

b855f671a5 rewrite to comply with latest spec
- correct sizes for the blocks : sec signature 65, ecies sklen 16, keylength 32
- added allocation to Xor (should be optimized later)
- no pubkey reader needed, just do with copy
- restructuring now into INITIATE, RESPOND, COMPLETE -> newSession initialises the encryption/authentication layer
- crypto identity can be part of client identity, some initialisation when server created
