Hello.
I want to know, why do i keep getting this error when implementing in active project. But this doesn't occured in fresh flutter project? using same certificate, same coding like this one :

  final bytes = await file.readAsBytes();
  final results = Pkcs12Utils.parsePkcs12(bytes,
    password: password,
  );
  final data = X509Utils.x509CertificateFromPem(results[1]);
  final map = <String, String?>{};

  for (MapEntry<String, String?> entry in data.tbsCertificate!.issuer.entries) {
    map[ASN1ObjectIdentifier.fromIdentifierString(entry.key).readableName ?? '-'] = entry.value;
 }

here is P12 data , with password "R3yn4ld1L0r3nz0"

Hello and thank you for the issue. The "parse" method is not yet finished and therefore there are still some bugs left. If time permits I will work on it and finish it. Currently it supports only the same algorithms that can be used in the generatePkcs12() method. I assume that the error comes up due to the PKCS12 you tried to parse was encrypted with AES, that is currently not supported or it is something else that is related to the fact that the "parsing logic" is not yet finished.
