PKI services
We operate a certificate authority (CA) and thus provide digital certificates. We offer both qualified certificates for electronic signatures, and advanced (non-qualified) certificates for advanced electronic signatures, encryption, user authentication, etc. Our root certificate is included in the default certificate repository of Windows. We also operate a time stamping authority that provides qualified timestamps that can prove that a certain document existed at a given time.
Systems relying on PKI
We develop and operate systems relying on PKI, and we prefer to include PKI elements in systems we develop during our other activities. For instance, Microsec develops and operates the IT services of Hungarian registry courts since 1990. Lawyers can found companies (on behalf of their clients) using their qualified electronic signatures, and they receive the official decision signed with the qualified electronic signature of the judge. Companies can also submit their annual reports with advanced electronic signatures, and these electronically signed, authentic documents are available to the general public. Most of these systems are based on the 'Mediator' technology developed by Microsec.
Signature creation application
The e-Szignó signature creation application can create e-dossiers that can encapsulate multiple signatures over multiple documents and can also store corresponding metadata, and thus they are particularly useful for supporting workflows based on electronic signatures.  e-Szignó signature creation application MicroSigner is a special web based electronic signature solution that is a substitution for Java applet and Microsoft ActiveX that are to be terminated soon. The solution assists to sign documents electronically in Windows and Mac OS operation systems either via PassBy[ME] or hardware with the help of keys stored on QSCD (Qualified Signature Creation Device) card.

Qualified long-term archiving
Long-term archiving requires a special, dedicated environment for both paper-based and electronically signed documents. A cryptographic algorithm that can be used for creating secure signatures today might become breakable in the future due to sudden advances in cryptoanalysis or in computational capabilities. Thus, there is a possibility that today's secure signatures become forgeable in the future. The Hungarian law on electronic signatures defines a service for the trusted (qualified) long-term archiving of electronically signed documents. Microsec was the first company in Hungary who is registered as a qualified long-term archiving service provider.


Information about the timestamp service provided by Microsec between October 3. 2019 and August 6. 2020
Microsec Ltd. hereby notifies its partners and all parties concerned that the following changes will occur in the verification methods of the ECC-based qualified timestamps issued by the qualified timestamping service provided between October 3. 2019 and August 6. 2020. The time stamping unit’s certificate "e-Szigno Qualified TSA 2019 02" (https://static.e-szigno.hu/tsa_certs/e-Szigno_Qualified_TSA_2019_02.cer) that was used to sign time stamps issued during the above period can only be verified based on the below provider certificates from 12 October 2020, 12:00.
Validity period for TLS/SSL Certificates changes to 1 year
Due to changes in regulatory requirements for trust service providers, the validity period for TLS/SSL Certificates issued after 31st August 2020 will change to 1 year. This change will also apply to PSD2 (EV QWAC) Certificates. TLS/SSL Certificates issued until 31st August will have the original 2-year validity period.
