Functions ¶
func BytesToInt64 ¶
BytesToInt64 converts byte array into int64. It returns converted integer, bytes read and err. err != nil if and only if binary.Varint returns an error.
func BytesToInt64FromReader ¶
BytesToInt64FromReader converts few first bytes into int64. It returns converted integer, bytes read and err. err != nil if and only if binary.Varint returns an error or given reader doesn't have that many bytes to read.
func BytesToInt64s ¶
BytesToInt64s converts result of Int64sToBytes back into []int64. It returns errors.WrongDataFormatError as an error when data doesn't appear to be a result of Int64sToBytes.
func BytesToInt8s ¶
BytesToInt8s converts []byte into []int8. Every byte in the slice is treated like it would be signed.
func Decrypt ¶
Decrypt decrypts encryptedData using NSE algorithm with given IV and key derived using DeriveKey function. It returns decryptedData and err. err != nil if len(data) < 1, len(data) != len(IV).
func Encrypt ¶
Encrypt encrypts data using NSE algorithm with given key derived using DeriveKey function. It returns encryptedData, IV and err. err != nil if len(data) < 1 or if GenerateIV function returned an error.
func GenerateIV ¶
GenerateIV generates IV of given length for NSE algorithm. It returns an error if length < 1 or if crypto.rand.Read returns an error.
func Int64ToBytes ¶
Int64ToBytes converts integer into byte array. It ignores padding, result is as short as possible. First byte is length of the rest.
func Int64sToBytes ¶
Int64sToBytes converts []int64 into []byte. For each int64 in the slice there is one byte indicating how many bytes to read next and those bytes.
func Int8sToBytes ¶
Int8sToBytes converts []int8 into []byte. Every int8 in the slice is treated like it would be unsigned.
