Certificate signature algorithm
RSA: SHA-256, SHA-384
*2
, SHA-512
*2
ECDSA: SHA-256, SHA-384, SHA-512
*1
Requirements for the certificate contained in a key are pursuant to CA certificates.
*2
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 certificate revocation list (CRL).
Definition of "Weak Encryption"
When [Prohibit Use of Weak Encrypt.] in [Encryption Settings] is set to [On], the use of the following algorithms is
prohibited. [Encryption Settings](P. 247)
Hash
MD4, MD5, SHA-1
HMAC
HMAC-MD5
Common key encryption
RC2, RC4, DES
Public key encryption
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 Key/Cert. with Weak Encryption] in [Encryption Settings] is set to [On], the hash
algorithm SHA-1, which is used for signing a root certificate, can be used.
