The <a href="https://factorable.net/">factorable.net</a> site provides
|
||
|
|
<a href="https://factorable.net/keycheck.html">key checker</a> to
|
||
|
|
verify whether weak or compromised key or not.
|
||
|
|
However this can only check X.509 certificate or SSH public key.
|
||
|
|
Thus you can't easily check your key before its certificate issuance
|
||
|
|
by PKCS#10 CSR (certificate signing request) or PKCS#8 PEM public key.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
This tool can generate a fake certificate by specifying CSR
|
||
|
|
for checking factorable weak key checker.
|
||
|
|
Resulting certificate has wrong signature value but it doesn't matter for the checker.
|
||
|
|
