| - | ===== A word of warning ===== | ||
| - | As with any security or cryptographic product, there are a number | ||
| - | of concerns that should be addressed. In order to use this product | ||
| - | securely, you should make an effort to obtain a thorough understanding | ||
| - | of its operation and the concepts involved. Improper usage is often | ||
| - | insecure usage, so please be sure to read the manual completely. | ||
| - | ==== Host Security ==== | ||
| - | The security of the computer running WinSCP is a serious | ||
| - | concern. Trojan Horse and Backdoor programs can potentially be used to | ||
| - | steal authentication credentials such as passwords and private keys | ||
| - | that have been stored or entered on the computer. Public computers | ||
| - | often have session monitoring software which may include key loggers, | ||
| - | or may have malicious software installed by a previous user. | ||
| - | |||
| - | WinSCP can support "keyboard-interactive" authentication | ||
| - | methods if offered by the server. With keyboard-interactive | ||
| - | authentication, the server can prompt for special credentials such | ||
| - | as a S/Key one-time password or RSA SecurID generated value. These | ||
| - | "disposable" credentials are preferable if you must use a public | ||
| - | computer. Contact your system administrator to find out if any form | ||
| - | of one-time authentication is offered. | ||
| - | ==== Stored Credentials ==== | ||
| - | WinSCP supports storing passwords with saved sessions. This is | ||
| - | provided as a convenience, and is not recommended. If you need to be | ||
| - | able to log in without reentering your credentials, the recommended | ||
| - | method is to use public key authentication and protect your private | ||
| - | key with a pass phrase. The SSH Key Agent provided by Putty, Pagent, | ||
| - | can store the decrypted key in memory, allowing you to enter your | ||
| - | credentials once and continue using them until you close down the | ||
| - | agent or log off of Windows entirely. | ||
| - | |||
| - | Saved passwords are stored in a manner that they can easily be | ||
| - | recovered. It is not possible to securely encrypt passwords in a way | ||
| - | that still allows for automatic use. Do not use the save password | ||
| - | feature if you are not absolutely sure of the physical and | ||
| - | electronic security of the system on which you are storing | ||
| - | passwords. | ||
