Examples ¶
Constants ¶
const ( // LowerLetters is the list of lowercase letters. LowerLetters = "abcdefghijklmnopqrstuvwxyz" // UpperLetters is the list of uppercase letters. UpperLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" // Digits is the list of permitted digits. Digits = "0123456789" // Symbols is the list of symbols. Symbols = "~!@#$%^&*()_+`-={}|[]\\:\"<>?,./" )
Variables ¶
var ( // ErrExceedsTotalLength is the error returned with the number of digits and // symbols is greater than the total length. ErrExceedsTotalLength = errors.New("number of digits and symbols must be less than total length") // ErrLettersExceedsAvailable is the error returned with the number of letters // exceeds the number of available letters and repeats are not allowed. ErrLettersExceedsAvailable = errors.New("number of letters exceeds available letters and repeats are not allowed") // ErrDigitsExceedsAvailable is the error returned with the number of digits // exceeds the number of available digits and repeats are not allowed. ErrDigitsExceedsAvailable = errors.New("number of digits exceeds available digits and repeats are not allowed") // ErrSymbolsExceedsAvailable is the error returned with the number of symbols // exceeds the number of available symbols and repeats are not allowed. ErrSymbolsExceedsAvailable = errors.New("number of symbols exceeds available symbols and repeats are not allowed") )
Functions ¶
func Generate ¶
Generate is the package shortcut for Generator.Generate.
Example ¶
res, err := Generate(64, 10, 10, false, false)
if err != nil {
log.Fatal(err)
}
log.Print(res)
Output:
func MustGenerate ¶
MustGenerate is the package shortcut for Generator.MustGenerate.
Example ¶
// Will panic on error res := MustGenerate(64, 10, 10, false, false) log.Print(res)
Output:
func PanicDetail ¶
func PanicDetail() string
func TimeoutedExec ¶
TimeoutedExec executes a timeouted command. The program path is defined by the name arguments, args are passed as arguments to the program.
TimeoutedExec returns process output as a string (stdout) , and stderr as an error.
Types ¶
type Generator ¶
type Generator struct {
// contains filtered or unexported fields
}
Generator is the stateful generator which can be used to customize the list of letters, digits, and/or symbols.
func NewGenerator ¶
NewGenerator creates a new Generator from the specified configuration. If no input is given, all the default values are used. This function is safe for concurrent use.
Example (Custom) ¶
// Customize the list of symbols.
gen, err := NewGenerator(&GeneratorInput{
Symbols: "!@#$%^()",
})
if err != nil {
log.Fatal(err)
}
_ = gen // gen.Generate(...)
Output:
Example (Nil) ¶
// This is exactly the same as calling "Generate" directly. It will use all
// the default values.
gen, err := NewGenerator(nil)
if err != nil {
log.Fatal(err)
}
_ = gen // gen.Generate(...)
Output:
func (*Generator) Generate ¶
func (g *Generator) Generate(length, numDigits, numSymbols int, noUpper, allowRepeat bool) (string, error)
Generate generates a password with the given requirements. length is the total number of characters in the password. numDigits is the number of digits to include in the result. numSymbols is the number of symbols to include in the result. noUpper excludes uppercase letters from the results. allowRepeat allows characters to repeat.
The algorithm is fast, but it's not designed to be performant; it favors entropy over speed. This function is safe for concurrent use.
Example ¶
gen, err := NewGenerator(nil)
if err != nil {
log.Fatal(err)
}
res, err := gen.Generate(64, 10, 10, false, false)
if err != nil {
log.Fatal(err)
}
log.Print(res)
Output:
type JWT ¶
type JWT struct {
// contains filtered or unexported fields
}
TODO: 结构体名称不太好
func (*JWT) FromContext ¶
func (this *JWT) FromContext(ctx context.Context) *Credential
func (*JWT) ParseToken ¶
func (this *JWT) ParseToken(input string) (cred Credential, err error)
ParseToken 解析令牌，生成凭证
