Depth is an SSH-2.0 implementation designed for authorized security assessments. The following behaviors are features, not bugs:

• Reverse and bind mode SSH server operation
• Encrypted communications (ChaCha20-Poly1305, TLS 1.3)
• Key exchange and host authentication (X25519, Ed25519)
• Interactive PTY shell access
• SFTP file transfer
• TCP port forwarding (local and remote)
• Small static binary with no dependencies

These capabilities exist by design for legitimate security testing. Reports that simply describe Depth working as intended will be closed.

Depth is intended for authorized penetration testing, security research, and educational purposes only. Users are responsible for ensuring they have proper authorization before using this tool against any systems.
