SignServer Signers

Signers are Workers that perform signing operations. A Signer specifies how to perform the signature creation, and which key and certificate to use.

There are multiple implementations of SignServer Signers available for signing different formats and additional implementations can be developed.

The following lists some of the available SignServer signers, grouped by use case.
