Its pretty straightforward. The passes don't match. I can't find why.
The hashing function
package utils
var hasher = md5.New()
func GetMD5Hash(text string) string {
fmt.Println(">> ", text, "<<")
hasher.Write([]byte(text))
return hex.EncodeToString(hasher.Sum(nil))
}
`
I make 1st restful call to create a user (register) calls this method.
func CreateUser(id bson.ObjectId, email string, password string) bool {
var user User
user.ID = id
user.Email = email
user.Password = utils.GetMD5Hash(password)
// fmt.Println("In Create User:", password, user.Password)
err := userCollection.Insert(&user)
if err != nil {
log.Println("Error while CreateUser")
return false
}
return true
}
Now I make 2nd restful call to authenticate (login)
The Authenticate User Method
func AuthenticateUser(email string, password string) bool {
user := GetUserByEmail(email)
var u User
u.Password = utils.GetMD5Hash(password)
fmt.Println("In Authenticate:", password, u.Password)
fmt.Println(u.Password, user.Password)
if u.Password == user.Password {
return true
}
return false
}
PASSWORDS DONT MATCH.
Results:

If it is not clear, I am literally making the same request repeatedly and every time results in a new MD5Hash. Also, both the register and login process uses the same UI, same text boxes different buttons.
Insights. Please.
It appears as though you are writing over and over to the same (package level variable) hasher, so that at first it contains 'pass', then 'passpass', then 'passpasspass' (as []byte of course) so the result changes because the underlying bytes are changing. Try putting in the var hasher = md5.New() inside the GetMD5Hash function.
