Full description
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 libraries from CurveCP implementation
reusing software - TinySSH is using tcpserver/systemd socket/inetd for TCP connection
limited amount of features - TinySSH doesn’t have features such: SSH1 protocol, compression, …
no older cryptographic primitives - rsa, dsa, classic diffie-hellman, hmac-md5, hmac-sha1, 3des, arcfour, …
no copyright restrictions - TinySSH is in the public domain (see the licence)
no dependency on OpenSSL - TinySSH has its own crypto library compatible with NaCl, Libsodium
speed - TinySSH can be also compiled using high-speed NaCl library instead of internal.
Security features
cryptographic library (minimum 128-bit security, side-channel attack resistant, state-of-the-art crypto, …)
public-key authentication only (no password or hostbased authentication)
