Frequently asked questions
Does successful parsing mean trusted certificates or protected key storage?
No. CA trust, certificate signatures and revocation are not verified. The password only opens the source PFX; extracted PKCS#8 keys and JSON containing keys are unencrypted. Protect downloaded files. Limits are 2 MiB, 20 certificates and 40 bags; unsupported PFX algorithms or contents are rejected.
