Requir
ements for the certicate contained in a key are pursuant to CA certicates.

SHA384-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 certicate r
evocation list (CRL).
Denition of "
Weak Encryption"
When [Prohibit Use of Weak Encryption] in [Encryption Settings] is set to [On], the use of the following algorithms is
prohibited.
[Encryption Settings](P. 458)
Hash MD4, MD5, SHA-1
HMAC HMAC-MD5
Common key encryption RC2, RC4, DES
Public key encryption RSA encryption (512 bits/1024 bits)
RSA signatur
e (512 bits/1024 bits)
DSA (512 bits/1024 bits)
DH (512 bits/1024 bits)
● Even when [Pr
ohibit Key/Cert. with Weak Encryption] in [Encryption Settings] is set to [On], the hash
algorithm SHA-1, which is used for signing a root certicate, can be used.
