This article examines how to increase your encryption level.

What does strong encryption do?

Enabling the use of strong encryption will only allow strong ciphers such as:

  • AES
  • 3DES

and digest

  • SHA1

for HTTPS/SSH admin access.

When strong encryption is enabled, HTTPS is supported by the following web browsers:

  • Netscape 7.2 -8.0
  • Firefox
  • Microsoft Internet Explorer 7.0 – 8.0

Microsoft Internet Explorer 5.0 and 6.0 are not supported in strong encryption.

How to enable strong encryption

To enable Strong Encryption run the following CLI command:

config sys global
  set strong-crypto enable
  end

To ”’disable”’ Strong Encryption run the following CLI command:

config sys global
  set strong-crypto disable
  end

The default setting for strong-crypto is disabled.

He has made the switch to technical writing as part of his deep, dark and dastardly plan to make the arcane machinations of IT technology more easily understood by the poor folks who use it. That, and the voices in his head told him it was good idea. Never argue with the voices in your head. People will start to stare.
