Key Features:
Wide range of authentication methods: All the VanDyke ClientPack applications support password, public-key (RSA, DSA, and Smart Cards using X.509), Kerberos v5 (via GSSAPI), and keyboard-interactive when connecting to SSH2 servers. vsh supports connections to SSH1 servers using password, public-key, and TIS authentications.

Extensive support for encryption ciphers: The VanDyke ClientPack applications support 3DES, RC4, Blowfish, Twofish, AES-128, AES-192, and AES-256 ciphers when connecting to SSH2 servers. The maximum 2048 bits length of DSA keys under SSH2 provides more secure encryption. For SSH1 servers, DES, 3DES, RC4, and Blowfish are supported.

Secure Shell: Secure Shell encrypted logon and session data, including support for the following:
- vsh port forwarding secures TCP/IP data
- X11 forwarding
- FIPS Mode uses a validated cryptographic library and only allows approved algorithms

File transfer utilities: vcp and vsftp command-line utilities secure file transfers using SFTP.
