Functions ¶

func CipherSize ¶

func CipherSize() int

CipherSize returns the size of the cipher used

func GenerateAESCipherBlock ¶

func GenerateAESCipherBlock(key []byte) (cipherBlock cipher.Block, err error)

GenerateAESCipherBlock generates the cipher used for encryption and decryption of data It takes in a byte array key and returns an error if the key is not of size 16, 24 or 32 or when the cipher failed to initialize.

func LastBlockSize ¶

func LastBlockSize(r *os.File) (size int, err error)

LastBlockSize reads the size of the last block from the beginning of the file

func SetCipher ¶

func SetCipher(cb cipher.Block)

SetCipher sets a cipher to be used for data encyption and decryption
