Storing .pfx file in mysql

Question

All,
I am trying to store a .pfx file in mysql.
What is the best way to do this?

Answer 1

I'm using mysql, no CLOB only BLOB.
Currently I am trying to base64 encode the .pfx text and store it into a longtext field.
The problem is when I retrieve it:
Exception in thread "main" java.io.IOException: toDerInputStream rejects tag type 114
        at sun.security.util.DerValue.toDerInputStream(DerValue.java:806)
        at com.sun.net.ssl.internal.pkcs12.PKCS12KeyStore.engineLoad(PKCS12KeyStore.java:1201)
        at java.security.KeyStore.load(KeyStore.java:1185)
        at com.emoneyadvisor.services.util.ThirdPartyCertificate.<init>(ThirdPartyCertificate.java:29)
        at emoneyjava.Emoney.main(Emoney.java:135)My cert is already made and I'm not going to change the format.
Any ideas on how I can easily resolve this?
I guess I understand that java is not understanding the format.
Here I get the contents of the cert file:
import com.Ostermiller.util.Base64;
public static String getFileContents(String filename) throws IOException {
          File file = new File(filename);
          InputStream is = new FileInputStream(file.getPath());
          // Get the size of the file
          long length = file.length();
          // Create the byte array to hold the data
          byte[] bytes = new byte[(int)length];
          // debug - init array
          for (int i = 0; i < length; i++){
               bytes[i] = 0x0;
          // Read in the bytes
          int offset = 0;
          int numRead = 0;
          while (offset < bytes.length && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
               offset += numRead;
          // Ensure all the bytes have been read in
          if (offset < bytes.length) {
               throw new IOException("Could not completely read file "+file.getName());
          // Close the input stream and return bytes
          is.close();
          String id = null;
          try {
          ByteArrayOutputStream baos = new
          ByteArrayOutputStream();
          ObjectOutputStream stream = new
          ObjectOutputStream(baos);
          stream.write(bytes);
          stream.flush();
          stream.close();
          id = new
          String(Base64.encode(baos.toByteArray()));
          } catch(Exception ex) {
          ex.printStackTrace();
          return id;
     }Using setString with PreparedStatement I add the cert to the LONGTEXT field.
Then I use this to retrieve the cert:
public static InputStream getCert(String coid){
     InputStream is = null;
     Connection conn = null;
     PreparedStatement pstmt = null;
     String sql = "select cert from table where coid = ? limit 1";
     String cert = null;
     try{
          conn = TradeHelper.connect();
          pstmt = conn.prepareStatement(sql);
          pstmt.setString(1, coid);          
          ResultSet rs = pstmt.executeQuery();
          while(rs.next()){
               cert = rs.getString("cert");
     }catch(Exception e){
          e.printStackTrace();
     }finally{
          try{
               TradeHelper.closeConnection(conn);
               pstmt.close();
          }catch(Exception e){
               e.printStackTrace();
     Base64.decode(cert);
     //lets get an inputstream on the cert.
     try {
          is = new ByteArrayInputStream(cert.getBytes("UTF-8"));
     } catch (UnsupportedEncodingException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
     return is;
