Invalid header when opening Twofish-encrypted database file

[vaygr]

Steps to reproduce:

1. Create a Twofish-encrypted database with KeePassXC
2. Run the code:

package main

import (
    "fmt"
    "github.com/tobischo/gokeepasslib/v3"
    "os"
)

func main() {
    file, _ := os.Open("/path/to/the/database.kdbx")

    db := gokeepasslib.NewDatabase()
    db.Credentials = gokeepasslib.NewPasswordCredentials("password")

    if err := gokeepasslib.NewDecoder(file).Decode(db); err != nil {
        fmt.Println("failed to decode db -", err)
    }
}

Error returned is gzip: invalid header. AES/ChaCha20 work fine.

@vaygr Thank you for raising the issue. Do you happen to have an example file? I am not using KeepassXC anywhere.

Maybe I am missing something but the original Keepass2 does not seem to have twofish as an option when creating new files.

[vaygr]

Yes, attaching it here (password test). I'm not sure about Keepass2, but in a widely used KeePassXC it's one of 3 options available.

Passwords.kdbx.zip

Interesting. In Keepass2 it is only those 2 options

I'll take a look and see what I can do

[tobischo]

Apparently it is possible to add twofish as a plugin in keepass2

@vaygr Please take a look at #110

[vaygr]

Thank you very much, that works as expected.

[tobischo]

Alright, will merge and release it probably this evening

[tobischo]

Released as v3.6.0

[vaygr]

Thank you for quickly resolving this!
