I fixed my import problem with .p12 cert files. My french version of MSIE 4.0 (4.72.2106.8) didn't accept private key with more than 512 bits. (Thanks to Kaur Virunurm [[EMAIL PROTECTED]]) I modify my script to use only 512 bits and all work fine. Question: What about security of these certs ? 512 are enough ?
