Functions

func RandomString

func RandomString(strLength int, allowedChars string) (string, error)

RandomString generates a random string of length strLength, composing only of characters in allowedChars. Based on code here: http://stackoverflow.com/a/9543797/483528 For convenience, the random package exposes various character sets you can use for the allowedChars parameter. Here are a few examples:

// Only lower case chars + digits random.RandomString(6, random.Digits + random.LowerLetters)

// alphanumerics + special chars random.RandomString(6, random.Base62Chars + random.SpecialChars)

// Only alphanumerics (base62) random.RandomString(6, random.Base62Chars)

// Only abc random.RandomString(6, "abc")
