SecureCRT implements all of the same great features found in its sister app, Combined Rlogin and Telnet (CRT), and adds advanced security capabilities of its own. In addition to supporting the standard telnet and rlogin protocols, the $99 SecureCRT also offers support for SSH 1.5 (Secure Shell), which includes DES, 3DES, and RC4 ciphers as well as both password and RSA authentication.
