Functions

func CheckPassword

func CheckPassword(password string, hashedPassword string) error

CheckPassword checks if the provided password is correct or not

func HashPassword

func HashPassword(password string) (string, error)

HashPassword returns the bcrypt hash of the password

func IsSupportedCurrency

func IsSupportedCurrency(currency string) bool

IsSupportedCurrency returns true if the currency is supported

func RandomCurrency

func RandomCurrency() string

RandomCurrency gera uma string representando uma moeda aleatória. Atualmente, a função retorna "BRL" como única opção, mas pode ser expandida para incluir mais moedas.

func RandomInt

func RandomInt(min, max int64) int64

RandomInt gera um inteiro aleatório entre min e max (inclusive). A função rand.Int63n gera um número aleatório entre max-min (+1, pois se der 0 ele retornará panic) e então adiciona min ao resultado para ajustar o intervalo.

func RandomMoney

func RandomMoney() int64

RandomMoney gera um valor int64 aleatório. A função utiliza RandomInt para gerar um valor inteiro aleatório entre 0 e 1000.

func RandomOwner

func RandomOwner() string

RandomOwner gera uma string aleatória de comprimento fixo. A função utiliza tools.RandomString do toolkit importado para criar uma string aleatória de 10 caracteres.
