Base64 digest is needed for creating CAdES signature using eID Easy /api/signatures/prepare-files-for-signing API call and signatureTime is needed later when completing the digital signature. 10 | 11 | - **POST /api/detached-pades/complete** - This call will get 3 json fields. signatureTime that was received when preparing, signatureValue that is CAdES signature created separately and fileContent that is the original file 12 | 13 | fileContent has to be sent in both calls because this is stateless service and does not save any data. 14 | 15 | ## Docker 16 | 17 | This application can be found from dockerhub also https://hub.docker.com/repository/docker/eideasy/pades-external-digital-signatures. 18 | 19 | To build locally use these commands 20 | ``` 21 | mvn clean package 22 | sudo docker build . --no-cache -t eideasy/pades-external-digital-signatures 23 | ``` 24 | 25 | Following will remove any existing instance and install new one that will listen to localhost port 8082. 26 | ``` 27 | sudo docker stop eideasy_detached_pades -t 0 28 | sudo docker rm eideasy_detached_pades 29 | sudo docker run -d -p 127.0.0.1:8082:8084 --name=eideasy_detached_pades --restart always --log-driver syslog --log-opt tag="{{.Name}}/{{.ID}}" eideasy/pades-external-digital-signatures 30 | ``` 31 | ## More info 32 | 33 | Postman documentation for these API calls can be found from https://documenter.getpostman.com/view/3869493/Szf6WoG1#bf3a86b8-3937-4b56-9579-a0e4751d2f18 34 | 35 | There is also free service for testing purposes running at https://detached-pdf.eideasy.com 36 | 37 | If you do not have any way to create ETSI.CAdES.detached digital signatures then you can use eID Easy service. Start with API call "/api/signatures/prepare-files-for-signing" and send the digest as the PDF file content.
