Python實現 SSHv2 協議的異步客戶端和服務器端：AsyncSSH

AsyncSSH這個 Python 包在Python asyncio框架的基礎實現 SSHv2 協議的異步客戶端和服務器端。求 Python 3.4 或者更新版本以及 PyCA 庫或者是 PyCrypto 庫用于加密功能。

顯著特征：

• Written from the ground up to be based on Python 3

• Support for a number of key exchange methods

  • Diffie Hellman group1 and group14 with SHA1
  • Diffie Hellman group exchange with SHA1 and SHA256
  • Elliptic Curve Diffie Hellman (nistp256, nistp384, and nistp521)
  • Curve25519 (if curve25519-donna Python wrapper is installed)

• Support for multiple authentication methods

  • Password, public key, and keyboard-interactive

• Support for a variety of public key formats

  • DSA, RSA, and ECDSA keys
  • PKCS#1/PKCS#8 DER and PEM, OpenSSH, and RFC4716 formats
  • Password-based encryption of private keys

• Support for a variety of ciphers (provided via PyCA or PyCrypto)

  • AES, ARC4, Blowfish, CAST, and Triple DES

• Support for a variety of MAC algorithms

  • HMAC with MD5, SHA1, SHA256, and SHA512

• Support for gzip compression

  • Including OpenSSH variant to delay compression until after auth

• Support for passing environment variables, terminal type, and window size

• Support for multiple simultaneous sessions on a single SSH connection

• Support for handling multiple SSH connections in a single event loop

• Support for direct and forwarded TCP/IP channels

• Support for both byte and string based I/O with settable encoding

• Compatibility with OpenSSH "Encrypt then MAC" option for better security

• Time and byte-count based session key renegotiation

• Designed to be easy to extend to support new forms of key exchange, authentication methods, ciphers, and compression algorithms
