Functions ¶

func Bytes ¶

func Bytes(size int) []byte

Bytes returns an amount of cryptographically-secure random bytes equal to the the specified size.

The bytes are generated using the crypto/rand package and will panic if crypto/rand fails to generate the requested amount of bytes.

Defaults to 32 if no size is specified.

func BytesWithReader ¶

func BytesWithReader(size int, reader io.Reader) []byte

BytesWithReader is like Bytes, but allows you to specify your own reader.

Types ¶

type UUID ¶

type UUID struct {
	// contains filtered or unexported fields
}

UUID represents a 128-bit Universal Unique Identifier (UUID) as defined in RFC 4122.

func (*UUID) GenerateV4 ¶

func (u *UUID) GenerateV4() string

Generate generates a UUIDv4 and returns it as a string.
