YADE should support Credential Store with Key Files for KeePass Version 1

Current Situation

• YADE supports use of credential stores from KeePass versions 1 and 2.
• When using a key file to secure the credential store then
  • this works for KeePass version 2.x
  • this does not work for KeePass versions 1.x, However use of a credential store secured by a password is reported to work.

Desired Behavior

• YADE should support use of key files with credentials stores managed by KeeePass versions 1.x
   

Maintainer Notes

• The usage of composite key with key file without master password for KeePass 1.x format is not supported.
• Composite keys support:
  • KeePass 1.x format
    • Master Password (without Key File) - supported
    • Key File (without Master Password) - not supported
      • Credential Store interface provides instead of IllegalStateException: Unknown field type xxxx exception an clearly defined error message -
        • the usage of composite key with key file without master password for KeePass 1.x format is not supported
      • The workaround is to us a dummy password with the key file or to use a KeePass2 credential store.
    • Master Password and Key File - supported
