Data type Range Default value
REG_DWORD 0 | 1 1


Determines whether outgoing secure channel traffic should be encrypted (sealed).

Channel traffic security is determined jointly by the value of this entry and the values of RequireStrongKey, requiresignorseal and signsecurechannel.

When requiresignorseal is set to 1, this entry determines whether encryption (sealing) is required for a secure channel. When requiresignorseal is set to 0, this entry specifies this system's preferences when negotiating with the domain controller on the other side of the channel. Also, because encryption is more secure than signing, when the value of this entry is 1, it takes precedence over the value of signsecurechannel.

Value Meaning
0 False. Outgoing traffic on a secure channel need not be encrypted. However, if the value of signsecurechannel is 1, outgoing traffic should be signed.
1 True. Outgoing traffic on a secure channel should be encrypted. This specification is enforced when the value of requiresignorseal is 1.
