Functions

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 

func EncodeArmor(blockType string, headers map[string]string, data []byte) string

func EncryptSymmetric 

func EncryptSymmetric(plaintext []byte, secret []byte) (ciphertext []byte)

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

func MixEntropy 

func MixEntropy(seedBytes []byte)

Mix additional bytes of randomness, e.g. from hardware, user-input, etc. It is OK to call it multiple times. It does not diminish security.

func Ripemd160 

func Ripemd160(bytes []byte) []byte

func Sha256 

func Sha256(bytes []byte) []byte
