小型的 SSH 服務器：TinySSH
TinySSH 是一個小型的 SSH 服務器，使用最先進的 NaCl / TweetNaCl 加密庫。提供基于 CurveCP 非常好的數據TCP傳輸安全性。
Features
- easy auditable - TinySSH has less than 100000 words of code
- no dynamic memory allocation - TinySSH has all memory statically allocated (less than 1MB)
- simple configuration - TinySSH can't be misconfigured
- reusing code - TinySSH is reusing build mechanism from NaCl and libraries from CurveCP implementation
- reusing software - TinySSH is using tcpserver/curvecpserver for TCP/CurveCP connection
- limited amount of features - TinySSH doesn't have features such: SSH1 protocol, compression, scp, sftp, ...
- no older cryptographic primitives - rsa, dsa, classic diffie-hellman, md5, sha1, 3des, arcfour, ...
- no copyright restrictions - TinySSH is in the public domain
- no dependency on OpenSSL - TinySSH is using NaCl / TweetNaCl
Security features
- using NaCl / TweetNaCl cryptographic library (minimum 128-bit security, side-channel attack resistant, state-of-the-art crypto, ...)
- public-key authentication only (no password or hostbased authentication)
Crypto primitives
- ssh-ed25519 + curve25519-sha256@libssh.org + chacha20-poly1305@openssh.com
- ready for ecdsa-sha2-nistp256, ecdh-sha2-nistp256, aes128-ctr/aes256-ctr, but disabled at this time
