The State Tax Service of Ukraine (hereinafter – STSU) has explained what should a taxpayer do if an “Incorrect password or damaged key” error occurs when signing an electronic document. More about this below.
To resolve this error, check:
- which qualified electronic signature key or seal is used first (correct sequence of signatures for tax reporting: accountant – director – electronic seal);
- correctness of password entry, namely: password entry register, keyboard language, etc. (the created password may contain special characters);
- whether the typed password corresponds to the key used (for example, the password to the accountant’s key is used only with the accountant’s key);
- whether the name of the private key file has been changed (in case of changing the file name the private key will be damaged, so it is necessary to contact a separate user registration point of the Qualified Provider of Electronic Trust Services of the STSU Information and Reference Department (hereinafter – QP ETS IRD STSU) where a qualified certificate was received, apply for a change in the status of a qualified certificate and receive a new set of registration documents).
If none of the recommendations helped to solve the problem, it is necessary to contact the representative office of the QP ETS IRD STSU, where qualified certificates were obtained, apply for revocation of a qualified certificate, generate a new private key and obtain the appropriate qualified certificates.
