Types of implementations

func CRandBytes

func CRandBytes(numBytes int) []byte

This uses the OS and the Seed(s).

func CRandHex

func CRandHex(numDigits int) string

RandHex(24) gives 96 bits of randomness, strong enough for most purposes.

func CReader

func CReader() io.Reader

Returns a crand.Reader mixed with user-supplied entropy

func DecodeArmor

func DecodeArmor(armorStr string) (blockType string, headers map[string]string, data []byte, err error)

func DecryptSymmetric

func DecryptSymmetric(ciphertext []byte, secret []byte) (plaintext []byte, err error)

secret must be 32 bytes long. Use something like Sha256(Bcrypt(passphrase)) The ciphertext is (secretbox.Overhead + 24) bytes longer than the plaintext.

func EncodeArmor
