Class ResetWindowsPassword

java.lang.Object

org.jclouds.googlecomputeengine.compute.functions.ResetWindowsPassword

All Implemented Interfaces:

com.google.common.base.Function<Map<String,?>,String>

public class ResetWindowsPassword
extends Object
implements com.google.common.base.Function<Map<String,?>,String>

References:

• automate-pw-generation
• windows_auth_java_sample.java

In brief, the sequence is:

1. Generate a temporary key for encrypting and decrypting the password
2. Send the RSA public key to the instance, by settings its metadata
3. Retrieve the result from the Instance.SerialPortOutput
4. Decode and decrypt the result.

Method Detail

apply

public String apply(Map<String,?> params)

Specified by:

apply in interface com.google.common.base.Function<Map<String,?>,String>

decryptPassword

protected String decryptPassword(String message,
                                 KeyPair keys)
                          throws InvalidKeyException,
                                 IllegalBlockSizeException,
                                 BadPaddingException

Decrypts the given password - the encrypted text is base64-encoded. As per the GCE docs, assumes it was encrypted with algorithm "RSA/NONE/OAEPPadding", and UTF-8.

Throws:

InvalidKeyException

IllegalBlockSizeException

BadPaddingException

extractKeyMetadata

protected Map<String,String> extractKeyMetadata(KeyPair pair,
                                                String userName,
                                                String email)
                                         throws NoSuchAlgorithmException,
                                                InvalidKeySpecException

Generates the metadata value for this keypair. Extracts the public key's the RSA spec's modulus and exponent, encoded as Base-64, and an expires date.

Parameters:

pair -

Returns:

Throws:

NoSuchAlgorithmException

InvalidKeySpecException
