## Random

package random import "github.com/averagesecurityguy/random"

```
The random package provides cryptographically secure random integers
and strings
```

## Functions

func Alpha(n uint64) (string, error)

```
Alpha returns a string of length n, which consists of random upper case
and lowercase characters. If n is less than or equal to zero then an
empty string is returned
```

func AlphaNum(n uint64) (string, error)

```
AlphaNum returns a string of length n, which consists of random
uppercase, lowercase, and numeric characters. If n is zero then an empty
string is returned.
```

func Chars(charset string, n uint64) (string, error)

```
Chars returns a random string of length n, which consists of the given
character set. If the charset is empty or n is less than or equal to
zero then an empty string is returned.
```

func Int16() (int16, error)

```
Int16 returns a random 16-bit signed integer. Return 0 and an error if
unable to get random data.
```

func Int32() (int32, error)

```
Int32 returns a random 32-bit signed integer. Return 0 and an error if
unable to get random data.
```

func Int64() (int64, error)

```
Int64 returns a random 64-bit signed integer. Return 0 and an error if
unable to get random data.
```

func Int8() (int8, error)

```
Int8 returns a random 8-bit signed integer. Return 0 and an error if
unable to get random data.
```

func Token() (string, error)

```
Token returns a string suitable for cryptographic tokens such as session
ids.
```

func Uint16() (uint16, error)

```
Uint16 returns a random 16-bit unsigned integer. Return 0 and an error
if unable to get random data.
```

func Uint32() (uint32, error)

```
Uint32 returns a random 32-bit unsigned integer. Return 0 and an error
if unable to get random data.
```

func Uint64() (uint64, error)

```
Uint64 returns a random 64-bit unsigned integer. Return 0 and an error
if unable to get random data.
```

func Uint64Range(start, end uint64) (uint64, error)

```
Uint64Range returns a random 64-bit unsigned integer in the range
[start, end]. An error is returned if start is greater than end.
```

func Uint8() (uint8, error)

```
Uint8 returns a random 8-bit unsigned integer. Return 0 and an error if
unable to get random data.
