Resolution

You may disable key length verification in the following way :

1) Edit file "..\Interchange\conf\jvmArguments.xml"
2) Add under "<!-- Common to all nodes --> " the line :
<Property key="com.entrust.toolkit.security.crypto.rsa.enforceAllowedFIPSKeyLength">false</Property>
3) Restart Interchange
4) Certificate will now be imported successfully
