See more DSA Examples

Converts a DSA private key from DER format to PEM. Demonstrates how to write both encrypted and unencrypted PEM formatted private keys. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final dsa = CkDsa();

  // Load a DER private key.
  try {
    dsa.fromDerFile('dsa_priv.der');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  var pemStr = '';

  // Save to unencrypted PEM:
  pemStr = dsa.toPem();
  try {
    dsa.saveText(pemStr, 'dsa_priv.pem');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Save to encrypted PEM:
  pemStr = dsa.toEncryptedPem('myPassword');
  try {
    dsa.saveText(pemStr, 'dsa_privEncrypted.pem');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Finished!');
