func (*CustomKeyInformation) Describe 

func (cki *CustomKeyInformation) Describe(indent int)

Describe prints a detailed description of the CustomKeyInformation instance.

Parameters: - indent: An integer representing the indentation level for the printed output.

Note: This function prints the Flags, VolumeType, SupportsNotification, FekKeyVersion, Strength, Reserved, and EncodedExtendedCKI values of the CustomKeyInformation instance. The output is formatted with the specified indentation level to improve readability.

func (*CustomKeyInformation) FromBytes 

func (cki *CustomKeyInformation) FromBytes(blob []byte, version KeyCredentialVersion) error

Parse parses the provided byte slice into the CustomKeyInformation structure.

Parameters: - blob: A byte slice containing the raw custom key information to be parsed.

Returns: - An error if the parsing fails, otherwise nil.

Note: The function expects the byte slice to follow the CUSTOM_KEY_INFORMATION structure format. It extracts the version, flags, volume type, supports notification, FEK key version, strength, reserved, and encoded extended CKI fields from the byte slice. The parsed values are stored in the CustomKeyInformation structure.

func (*CustomKeyInformation) ToBytes 

func (cki *CustomKeyInformation) ToBytes() []byte

ToBytes returns the raw bytes of the CustomKeyInformation structure.

type CustomKeyInformationFlags 

type CustomKeyInformationFlags struct {
	Value uint8
	Name  []string

	// Internal
	RawBytes     []byte
	RawBytesSize uint32
}

CustomKeyInformationFlags represents custom key flags.

See: https://msdn.microsoft.com/en-us/library/mt220496.aspx

func (*CustomKeyInformationFlags) FromBytes 

func (kf *CustomKeyInformationFlags) FromBytes(value byte)

Parse parses the provided byte slice into the CustomKeyInformationFlags structure.

Parameters: - value: A byte slice containing the raw key flags to be parsed.

Note: The function expects the byte slice to contain a single byte representing the key flags. It extracts the flags value from the byte slice and assigns it to the CustomKeyInformationFlags structure.

type CustomKeyInformationVolumeType 

type CustomKeyInformationVolumeType struct {
	Value uint8

	// Internal
	RawBytes     []byte
	RawBytesSize uint32
}

CustomKeyInformationVolumeType represents the volume type.

func (*CustomKeyInformationVolumeType) Describe 

func (vt *CustomKeyInformationVolumeType) Describe(indent int)

Describe prints a detailed description of the CustomKeyInformationVolumeType instance.

Parameters: - indent: An integer representing the indentation level for the printed output.

Note: This function prints the Value and Name of the CustomKeyInformationVolumeType instance. The output is formatted with the specified indentation level to improve readability.

func (*CustomKeyInformationVolumeType) FromBytes 

func (vt *CustomKeyInformationVolumeType) FromBytes(value byte)

Parse parses the provided byte slice into the CustomKeyInformationVolumeType structure.

Parameters: - value: A byte slice containing the raw volume type to be parsed.

Note: The function expects the byte slice to contain a single byte representing the volume type. It extracts the volume type value from the byte slice and assigns it to the CustomKeyInformationVolumeType structure.
