Undersign.js – JavaScript library for creating digital signatures

Undersign.js is a JavaScript library for creating eIDAS-compliant XAdES digital signatures and ASiC-E containers.

Undersign.js has built-in support for the use of the Estonian ID-card, Mobile-ID and Smart-ID services, but can also be used with other trust services.

Since 2020, Undersign.js has successfully processed more than half a million digital signatures on the Rahvaalgatus.ee platform.
