func (WrappingKey) DeserializeEncryptedDataKey ¶
func (wk WrappingKey) DeserializeEncryptedDataKey(b []byte, iVLen int) (encryptedData, iv []byte)
DeserializeEncryptedDataKey reverses the process of SerializeEncryptedDataKey. It takes a single byte slice containing the serialized encrypted data key, tag, and IV and extracts the original components. This is typically used to retrieve the encrypted key and IV for decryption purposes.
Parameters:
b []byte: A byte slice that contains the serialized encrypted data key,
authentication tag, and IV.
iVLen int: The length of the IV, which dictates how many bytes to extract
from the end of the byte slice for the IV.
Returns:
encryptedData []byte: The portion of the byte slice 'b' that represents the
encrypted data key (and potentially the authentication
tag if it is included with the encrypted data).
iv []byte: The extracted initialization vector that was originally
used for encryption.
func (WrappingKey) SerializeEncryptedDataKey ¶
func (wk WrappingKey) SerializeEncryptedDataKey(encryptedKey, tag, iv []byte) []byte
SerializeEncryptedDataKey takes three separate byte slices that represent the encrypted key, the authentication tag, and the initialization vector (IV), and concatenates them into a single byte slice.
Parameters:
encryptedKey []byte: A byte slice representing the encrypted data key.
tag []byte: A byte slice representing the authentication tag
used to verify the integrity of the encrypted data.
iv []byte: A byte slice representing the initialization vector
used during the encryption process.
Returns:
[]byte: A concatenated byte slice that includes the encrypted key, followed
by the authentication tag, and ending with the IV.
