base64Encode

public static byte[] base64Encode(byte[] in)
                           throws IOException

Encodes a byte array into base-64.

Parameters:

in - the byte array to be encoded.

Returns:

the base-64 encoded bytes as a byte array.

Throws:

IOException - on encoding errors.

base64Decode

public static byte[] base64Decode(byte[] in)
                           throws IOException

Decodes a base-64 encoded byte array.

Parameters:

in - the byte array to be decoded.

Returns:

the base-64 decoded bytes as a byte array.

Throws:

IOException - on decoding errors.

toPEMEncoding

public static byte[] toPEMEncoding(X509Certificate cert)
                            throws PKIException

Returns the PEM encoding of an X.509 certificate.

i.e. the base-64 encoded certificate bounded by a header and footer of the form

  -----BEGIN CERTIFICATE-----

  -----END CERTIFICATE-----
 

Parameters:

cert - the X509Certificate to be encoded.

Returns:

the encoded bytes as a byte array.
