c60d5b31c6 -Added Poly1305-Chacha20 cipher (new hardcoded default) 
-Use HMAC and CTR/CBC from libcrash instead of our own implementations
-Fixed stack allocation for keystroke handler thread

553742f877 libcrash: sync with upstream. 
* Implement new algorithms:
  - MACs: Poly1305, HMAC (SHA2_256, SHA2_512),
  - ciphers: ChaCha20, AES256CTR, AES256CBC.
* Remove MD4 hash.
* Change API (it happens).
* Update crashtest example.

33d98adcfa Implemented local storage and checking of remote host keys. (only ssh-rsa for now) 
Known public keys will be stored in /sys/settings/known_hosts.ini

67b03ef814 Big refactor: separate backend from frontend. Prepare for dynamically negotiated algorithms etc. 
New: RSA host authentication, use new con_get_input from console.lib to get escape codes from special keys, UTF8 to CP866 decoder, ..
Bugfix: CTR counters.

4f24fcab0f Pad with 0 bytes before encryption is set, as not to leak any entropy of RNG. 
Little improved RNG seeding.
Fixed bug in MAC counter for SSH transport.

66f0a0e45d SSH: Added user authentication. Fixed padding. Other bugfixes. 
Changed hardcoded encryption mode from AES256-CBC to AES256-CTR.
Added blowfish encryption algorithm code.
MPINT: Improved multi precision math routines. Variable length MPINTS, leading zeroes allowed but not nescessary. Other bugfixes.
Added tests vectors for MPINT routines.

a70850fad6 Working encryption and HMAC for transport, use libcrash for sha256 (and more to come), placed connection variables in separate struct, fixed bug in aes256_cbc_decode where IV was wrong when in- and output buffer were the same.
