Functions

func AppendSequence

func AppendSequence[T any](n int, charset, output []T) []T

AppendSequence generates a random sequence of the given length using the given character set and appends it to the given output slice.

func Bytes

func Bytes(n int) []byte

Bytes generates the given amount of random bytes using crypto/rand, and panics if it fails.

func GetTokenPrefix

func GetTokenPrefix(token string) string

GetTokenPrefix parses the given token generated with Token, validates the checksum and returns the prefix namespace.

func IsToken

func IsToken(namespace, token string) bool

IsToken checks if the given token is a valid token generated with Token with the given namespace..

func String

func String(n int) string

String generates a random string of the given length.

func StringBytes

func StringBytes(n int) []byte

StringBytes generates a random string of the given length and returns it as a byte array.

func StringBytesCharset

func StringBytesCharset(n int, charset string) []byte

StringBytesCharset generates a random string of the given length using the given character set and returns it as a byte array. Note that the character set must be ASCII. For arbitrary Unicode, use AppendSequence with a `[]rune`.

func StringCharset

func StringCharset(n int, charset string) string

StringCharset generates a random string of the given length using the given character set. Note that the character set must be ASCII. For arbitrary Unicode, use AppendSequence with a `[]rune`.

func Token

func Token(namespace string, randomLength int) string

Token generates a GitHub-style token with the given prefix, a random part, and a checksum at the end. The format is `prefix_random_checksum`. The checksum is always 6 characters.
