Error when importing SSL certificate into LTM

Hi B_Stephen,

If your intention is how to use openssl for the same task from LTM, you can use open source Filezilla sftp client (you need to download that) or any other sftp client and connect to LTM (root@ltm_mgmt_ip_addr) and store it for e.g. in /var/tmp.

Then from LTM, you can use openssl command to view it.

e.g. I have a cert in PEM format called "abc-client2-cert.pem".

[root@mks116:Active:Standalone] tmp  openssl x509 -in /var/tmp/abc-client2-cert.pem -text -noout

If your cert is in DER format, then use:

openssl x509 -inform DER -in ./abc-client2-cert.der -text -noout

Alternatively you can install CYGWIN on Windows (to get a unix like environment) and install openssl in it. Then you can do all openssl stuff from Windows itself.
