Method Detail

convertToDefiniteLength

public static byte[] convertToDefiniteLength(byte[] berPKCS12File)
                                      throws java.io.IOException

Just re-encode the outer layer of the PKCS#12 file to definite length encoding.

Parameters:

berPKCS12File - - original PKCS#12 file

Returns:

a byte array representing the DER encoding of the PFX structure

Throws:

java.io.IOException

convertToDefiniteLength

public static byte[] convertToDefiniteLength(byte[] berPKCS12File,
                                             char[] passwd,
                                             java.lang.String provider)
                                      throws java.io.IOException

Re-encode the PKCS#12 structure to definite length encoding at the inner layer as well, recomputing the MAC accordingly.

Parameters:

berPKCS12File - - original PKCS12 file.

provider - - provider to use for MAC calculation.

Returns:

a byte array representing the DER encoding of the PFX structure.

Throws:
