EU-Digital-COVID-Certificate-UVCI-Parser

Tool to parse & verify EU Digital COVID Certificate UVCI (Unique Vaccination Certificate/Assertion Identifier)

See Rust community’s crate registry for documentation

Following the conclusions of the European Council of 10-11 December 2020 and of 21 January 2021 that called for “a coordinated approach to vaccination certificates”, these guidelines establish a unique identifier for vaccination certificates. This software library parses and verifies the EU Digital COVID Certificate UVCI according to eHealth Network Guidelines on ‘verifiable vaccination certificates - basic interoperability elements’ - Release 2. The inclusion of the checksum is optional. The prefix “URN:UVCI:” may be added. Verification is performed by this crate.

Only for Sweden EHM-issued COVID certificates: Export a vector of EU Digital COVID Certificate UVCIs to Neo4j Cypher Graph. Parsing of Swedish UVCI ‘Opaque Unique String’ is experimental. The Swedish vaccination dates are derived from the UVCI aganist national statistics for vaccination against COVID-19. The statistics is from the Public Health Agency of Sweden (Folkhalsomyndigheten) based on cumulatively number of vaccinations per week. The Swedish vaccination dates are predicted with an accuracy of approximately +/- 1 month. Test UVCI is generated using software from Sweden’s Agency for Digital Government (Myndigheten för digital förvaltning).
