php editor Baicao may encounter "undefined" problems when using Golang Gorm Fiber and argon2.Config. This problem is mainly caused by the lack of corresponding definition or configuration. To solve this problem, we need to check whether the corresponding libraries and configurations are introduced correctly, and ensure that they are used and called correctly in the code. With careful inspection and debugging, we can resolve this issue and get our code to run properly.
I'm trying to switch from PHP to GO but I'm stuck and I'm asking for your help.
I'm trying to create a cryptographic hash function using Argon2, but I keep getting the error "Undefined: argon2.Config" when I use "argon2.Config{}". I've recompiled the project multiple times but can't seem to find a solution. I'm asking for your help in resolving this issue.
func hashPassword(password string) []byte { // Şifreleme parametreleri timeCost := 1 // İşlem süresi memory := 64 * 1024 // // Bellek miktarı threads := 4 // İş parçacığı sayısı keyLength := 32 // Oluşturulacak hash uzunluğu salt := []byte("unique_salt") // Her kullanıcı için benzersiz // Argon2 işlemi için hasher oluştur hasher := argon2.Config{ Time: uint32(timeCost), Memory: uint32(memory), Threads: uint8(threads), KeyLen: uint32(keyLength), } // Şifreyi hashle hashedPassword := hasher.Hash(password, salt, nil) return hashedPassword }
If you use the package "golang.org/x/crypto/argon2"
you can use the argon2.IDKey()
method. Here is a working example:
func HashPassword(password string) (hashedPassword string) { const ( timeCost uint32 = 1 // İşlem süresi memory uint32 = 64 * 1024 // // Bellek miktarı threads uint8 = 4 // İş parçacığı sayısı keyLength uint32 = 32 // Oluşturulacak hash uzunluğu ) salt := []byte("unique_salt") // Her kullanıcı için benzersiz // generate hashedpassword hash := argon2.IDKey([]byte(password), salt, timeCost, memory, threads, keyLength) // Base64 encode the salt and hashed password. b64Salt := base64.RawStdEncoding.EncodeToString(salt) b64Hash := base64.RawStdEncoding.EncodeToString(hash) format := "$argon2id$v=%d$models=%d,t=%d,p=%d$%s$%s" // final password in recommended format hashedPassword = fmt.Sprintf(format, argon2.Version, memory, timeCost, threads, b64Salt, b64Hash) return hashedPassword }
