func GenerateRandomBytes ¶

func GenerateRandomBytes(n int) ([]byte, error)

GenerateRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func GenerateUuidV4 ¶

func GenerateUuidV4() (string, error)

GenerateUuidV4 will generate a uuid that is a valid v4 uuid (https://tools.ietf.org/html/rfc4122) The version 4 UUID is meant for generating UUIDs from truly-random or pseudo-random numbers.

The algorithm is as follows:

o Set the two most significant bits (bits 6 and 7) of the clock_seq_hi_and_reserved to zero and one, respectively.

o  Set the four most significant bits (bits 12 through 15) of the

time_hi_and_version field to the 4-bit version number from Section 4.1.3.

o  Set all the other bits to randomly (or pseudo-randomly) chosen

values.
