1fge0fcbccabda0g0a01ffc0To use as a library is pretty simple:
config := generator.Config{
Length: 16,
IncludeSymbols: false,
IncludeNumbers: true,
IncludeLowercaseLetters: true,
IncludeUppercaseLetters: true,
ExcludeSimilarCharacters: true,
ExcludeAmbiguousCharacters: true,
}
g, _ := generator.New(&config)
pwd, _ := g.Generate()
// pwd = 8hp43B2R7gaXrZUW
pwds, _ := g.GenerateMany(5)
// pwds = [
// dnPp2TW2e8wmkAwT,
// XVYwWn25xuNwhUTy,
// vQ8aSrustQzxQCkA,
// AuT4fu5RU9TtxEUR,
// muDwwBRpKpC5BcHr,
// ]
pwd, _ = g.GenerateWithLength(12)
// pwd = HHhpzRGsmEWt
pwds, _ := g.GenerateManyWithLength(5, 12)
// pwds = [
// s5TKYPdgRzvZ
// wZFgzs8PUvRg
// tU73qZ9sPzEs
// mMaYU6hkvxPQ
// KBNZ2D7cVQS2
// ]The library also comes with some helper constants:
const (
// LengthWeak weak length password
LengthWeak = 6
// LengthOK ok length password
LengthOK = 12
// LengthStrong strong length password
LengthStrong = 24
// LengthVeryStrong very strong length password
LengthVeryStrong = 36
// DefaultLetterSet is the letter set that is defaulted to - just the
// alphabet
DefaultLetterSet = "abcdefghijklmnopqrstuvwxyz"
// DefaultLetterAmbiguousSet are letters which are removed from the
// chosen character set if removing similar characters
DefaultLetterAmbiguousSet = "ijlo"
// DefaultNumberSet the default symbol set if character set hasn't been
// selected
DefaultNumberSet = "0123456789"
// DefaultNumberAmbiguousSet are the numbers which are removed from the
// chosen character set if removing similar characters
DefaultNumberAmbiguousSet = "01"
// DefaultSymbolSet the default symbol set if character set hasn't been
// selected
DefaultSymbolSet = "!$%^&*()_+{}:@[];'#<>?,./|\\-=?"
// DefaultSymbolAmbiguousSet are the symbols which are removed from the
// chosen character set if removing ambiguous characters
DefaultSymbolAmbiguousSet = "<>[](){}:;'/|\\,"
