IPSec supports communication to a unicast address (or a single device).
The machine cannot use both IPSec and DHCPv6 at the same time.

*1Requirements for the certificate contained in a key are pursuant to CA certificates.
*2SHA384-RSA and SHA512-RSA are available only when the RSA key length is 1024 bits or more.

The machine does not support use of a certificate revocation list (CRL).

Hash:

HMAC:
|
HMAC-MD5

Common key cryptosystem:
|
RC2, RC4, DES
|
Public key cryptosystem:
|
RSA encryption (512 bits/1024 bits), RSA signature (512 bits/1024 bits), DSA (512 bits/1024 bits), DH (512 bits/1024 bits)
|
Even when <Prohibit Weak Encryp. Key/Cert.> is set to <On>, the hash algorithm SHA-1, which is used for signing a root certificate, can be used.
