class dissect.hypervisor.descriptor.vmx.VMX(vm_settings: Dict[str, str])#
property encrypted: bool#

Return whether this VMX is encrypted.

Encrypted VMXs will have both a encryption.keySafe and encryption.data value. The encryption.keySafe is a string encoded KeySafe, which is made up of key locators.

For example:


A KeySafe must be a list of Pairs. Each Pair has a wrapped key, an HMAC type and some encrypted data. It’s implementation specific how to unwrap a key. E.g. a phrase is just PBKDF2. The unwrapped key can be used to unlock the encrypted Pair data. This will contain the final encryption key to decrypt the data in encryption.data.

So, in summary, to unseal a KeySafe: Parse KeySafe -> iterate pairs -> unlock Pair -> unwrap key (e.g. Phrase) -> decrypt Pair data -> parse dict

The terms for unwrapping, unlocking and unsealing are taken from VMware.

classmethod parse(string: str) VMX#

Parse a VMX dictionary from a string.

unlock_with_phrase(passphrase: str) None#

Unlock this VMX in-place with a passphrase if it’s encrypted.

This will load the KeySafe from the current dictionary and attempt to recover the encryption key from it using the given passphrase. This key is used to decrypt the encrypted VMX data.

The dictionary is updated in-place with the encrypted VMX data.

disks() List[str]#

Return a list of paths to disk files

class dissect.hypervisor.descriptor.vmx.KeySafe(locators: List[Pair])#
unseal_with_phrase(passphrase: str) bytes#

Unseal this KeySafe with a passphrase and return the decrypted key.

classmethod from_text(text: str) KeySafe#

Parse a KeySafe from a string.

class dissect.hypervisor.descriptor.vmx.Pair(wrapped_key, mac: str, data: bytes)#

Return repr(self).

has_phrase() bool#

Return whether this Pair is a Phrase pair.

unlock(*args, **kwargs) bytes#

Helper method to unlock this Pair for various wrapped keys.

Currently only supports Phrase.

unlock_with_phrase(passphrase: str) bytes#

Unlock this Pair with a passphrase and return the decrypted data.

class dissect.hypervisor.descriptor.vmx.Phrase(id: str, pass2key: str, cipher: str, rounds: int, salt: bytes)#

Return repr(self).

unwrap(passphrase: str) bytes#

Unwrap/generate the encryption key for a given passphrase.

VMware calls this unwrapping, but really it’s a KDF with the properties of this Phrase.
