Overview

Package cipher provides an encryption and decryption interface.

It abstracts from the used cipher algorithm

Functions

func Decrypt

func Decrypt(dst, src []byte) (c int)

Decrypt converts src into dst and returns count of converted bytes. Only multiple of 8 are convertable, so last 0-7 bytes are not convertable and c is a multiple of 8. The smaller byte slice limits the conversion.

func Decrypt8

func Decrypt8(b []byte) (d []byte)

Decrypt8 translates an Encrypt protected byte slice back in a slice of length 8.

Shorter slices are extented with 0 until length 8. Langer slices are truncated to length 8.

func Encrypt

func Encrypt(dst, src []byte) (c int)

Encrypt converts src into dst and returns count of converted bytes. Only multiple of 8 are convertable, so last 0-7 bytes are not convertable and c is a multiple of 8. The smaller byte slice limits the conversion.

func Encrypt8

func Encrypt8(b []byte) (e []byte)

Encrypt8 translates a byte slice in a protected slice of length 8.

Shorter slices are extented with 0x16 until length 8. Langer slices are truncated to length 8.

func SetUp

func SetUp() error

SetUp uses the Password to create a cipher. If Password is "" encryption/decryption is disabled.
