You can use the Java keytool key and certificate management utility to create an SSL certificate or a certificate signing request (CSR) as well as keystores and truststores in JKS format.
The keytool utility is available in the following directory on domain nodes:
<Informatica installation directory>\java\bin
If the domain nodes run on AIX, you can use the keytool provided with the IBM JDK to create an SSL certificate or a Certificate Signing Request (CSR) as well as keystores and truststores.
You can use OpenSSL to create an SSL certificate or CSR as well as convert a keystore in JKS format to PEM format.
For more information about OpenSSL, see the documentation on the following website:
