Example: Write in existing DB and rootGroup

[nullsoft8411]

Hallo @tobischo can we have a example to write in existing DB and rootGroup? the entry should be added as subGroup.

Hi @nullsoft8411,

I don't really understand the question? While yes, there is not 1 example that does everything, it is pretty much just a combination of the reading and writing example.

The basic flow would be:

• Read the file https://github.com/tobischo/gokeepasslib/blob/master/examples/reading/example.go#L13-L15
• Unlock protected entries https://github.com/tobischo/gokeepasslib/blob/master/examples/reading/example.go#L17
• Select the root group
• Create the sub group https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L43-L45
• Create the new entry https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L47-L50
• Add the entry to the group https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L52
• Add the sub group to the root group https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L54
• Lock the protected entries again https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L69
• Write the new file https://github.com/tobischo/gokeepasslib/blob/master/examples/writing/example-writing.go#L72-L75

I haven't tested that against an example but it should look roughly like this:

file, err := os.Open("./example.kdbx")
if err != nil {
  log.Fatalf("Failed to open DB file: %s", err)
}

db := gokeepasslib.NewDatabase()
db.Credentials = gokeepasslib.NewPasswordCredentials("abcdefg12345678")
err = gokeepasslib.NewDecoder(file).Decode(db)
if err != nil {
  log.Fatalf("Failed to decode DB: %s", err)
}

db.UnlockProtectedEntries()

rootGroup := db.Content.Root.Groups[0]

subGroup := gokeepasslib.NewGroup()
subGroup.Name = "sub group"

subEntry := gokeepasslib.NewEntry()
subEntry.Values = append(subEntry.Values, mkValue("Title", "Another password"))
subEntry.Values = append(subEntry.Values, mkValue("UserName", "johndough"))
subEntry.Values = append(subEntry.Values, mkProtectedValue("Password", "123456"))

subGroup.Entries = append(subGroup.Entries, subEntry)

rootGroup.Groups = append(rootGroup.Groups, subGroup)

db.Content.Root.Groups[0] = rootGroup

db.LockProtectedEntries()

// and encode it into the file
keepassEncoder := gokeepasslib.NewEncoder(file)
if err := keepassEncoder.Encode(db); err != nil {
  log.Fatalf("Failed to write DB file: %s", err)
}
