tokengen
tokengen is small, simple and flexible token generator. tokengen allows you to specify your character set and token length, and as such is ideally suited for generating secure tokens in any language, random urls, passwords, and access tokens.
tokengen relies on the crypto/rand package, mapping values evenly to the character set
given, disregarding any values out of range.
func GenerateOneTimePassword() (string, error){
tokengen, err := tokengen.New(tokengen.DefaultCharset, 40)
if err != nil {
return tokengen, err
}
return tokengen.GenerateToken()
}
Please make sure that the character set and length of token you choose are large enough to ensure a reasonable amount of entropy.

Overview ¶
Package tokengen provides a simple way to generate secure tokens of any length from any character set. Allowing for easy password, url, and token generation.

Constants ¶
const ( // Base62 [A-Za-z0-9] Base62 = `0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz` // Base64 [A-Za-z0-9+/] Base64 = Base62 + `+/` // DefaultCharset Base62 DefaultCharset = Base62 )

Types ¶
type TokenProvider ¶
TokenProvider is a simple interface for abstracting token provisioning.
type Tokengen ¶
type Tokengen struct {
// contains filtered or unexported fields
}
Tokengen implements TokenProvider and contains the configuration for generating cryptographically secure tokens.
func (Tokengen) GenerateToken ¶
GenerateToken will provide a string of letters, picked at random from the given character set, with even distribution of runes from the set GenerateToken relies on the crypto/rand package for it's random data source, rather than the math package, so is ideally suited for secure uses such as password, token and url generation.
func GenerateOneTimePassword() (string, error){
tokengen, err := tokengen.New(tokengen.DefaultCharset, 12)
if err != nil {
return ``, err
}
return tokengen.GenerateToken()
}
