Features

• Read X.509 certificate fields from a PKCS#12 (.pfx / .p12) file on Android and iOS.
  • Subject DN and individual fields: Common Name (CN), Organization (O), Organizational Unit (OU), Country (C), Email (E)
  • Issuer DN
  • Validity dates: notBefore and notAfter
  • Serial number
• Two input methods:
  • PfxReader.fromBytes(Uint8List, password) — load from raw bytes (e.g. from an asset or file picker)
  • PfxReader.fromFile(String path, password) — load from a file path on disk
• Sign arbitrary data using the private key embedded in the PFX:
  • PfxReader.signWithBytes(data, pfxBytes, password)
  • PfxReader.signWithFile(data, filePath, password)
  • Supported algorithms: SHA256withRSA (default), SHA1withRSA, SHA512withRSA
• Typed PfxException with PfxErrorCode enum instead of raw PlatformException:
  • wrongPassword — incorrect PFX password
  • fileNotFound — file path does not exist
  • importError — corrupt or unsupported PFX format
  • keyError — private key could not be extracted
  • signError — signing operation failed
  • unknown — unexpected error

Platform implementation details

• Android: uses java.security.KeyStore (PKCS12 provider) and java.security.Signature
• iOS: uses SecPKCS12Import for import/signing, and a pure Swift ASN.1 DER parser for certificate field extraction (no macOS-only APIs, fully compatible with iOS simulator and device)
