Usage

From source file:org.apache.kerby.pkix.PkiLoader.java

private PrivateKey doLoadPrivateKey(InputStream inputStream, String password)
        throws GeneralSecurityException, IOException {
    if (password == null) {
        password = "";
    }// w w  w.  j  a va2  s.  c o m
    // If the provided InputStream is encrypted, we need a password to decrypt
    // it. If the InputStream is not encrypted, then the password is ignored
    // (can be null).  The InputStream can be DER (raw ASN.1) or PEM (base64).
    PKCS8Key pkcs8 = new PKCS8Key(inputStream, password.toCharArray());

    // If an unencrypted PKCS8 key was provided, then this actually returns
    // exactly what was originally passed inputStream (with no changes).  If an OpenSSL
    // key was provided, it gets reformatted as PKCS #8 first, and so these
    // bytes will still be PKCS #8, not OpenSSL.
    byte[] decrypted = pkcs8.getDecryptedBytes();
    PKCS8EncodedKeySpec spec = new PKCS8EncodedKeySpec(decrypted);

    // A Java PrivateKey object is born.
    PrivateKey pk = null;
    if (pkcs8.isDSA()) {
        pk = KeyFactory.getInstance("DSA").generatePrivate(spec);
    } else if (pkcs8.isRSA()) {
        pk = KeyFactory.getInstance("RSA").generatePrivate(spec);
    }

    // For lazier types:
