IT Centre CI

Ladies and gentlemen,

due to the safety of users, the final withdrawal of the SHA-1 algorithm from all ePUAP environments and the Trusted Profile (PZ) system will take place on March 11, 2022.

Entities not adapted to the changes in question, I would like to inform you that the implementation of the SHA-256 hash function will take place regardless of their readiness. I oblige you to immediately move in your software and ICT systems communicating with ePUAP and PZ to use the recommended hash function SHA-256. At the same time, I would like to inform you that the lack of adjustment within the prescribed period will prevent communication with ePUAP and PZ.

If you have any questions regarding the above information, I encourage you to establish cooperation with the Service Desk of the Central IT Center:

      • Telephone: + 48 (42) 253 54 50 open Mon. - Fri from 7:00 a.m. to 6:00 p.m.
      • E-mail address: pz-pomoc@coi.gov.pl and epuap-pomoc@coi.gov.pl 

Yours faithfully,
Maciej Górski
Director
Systems Management Department
Chancellery of the Prime Minister
