Additional EP11 documentation

Edit online

You can obtain two additional PDF files with information about the EP11 library structure and the wire format.

The EP11 Support Program that you can download as described in step 1 of TKE setup for EP11 also contains the following documentation, which is of interest for developers who want to use the EP11 library directly by linking it to the application, in contrast to use it by exploiting the openCryptoki EP11 token, or who want to write an alternative EP11 library:

  • file ep11-structure.pdf contains documentation about the EP11 library, a cryptographic service provider (CSP) backend providing services typical of hardware security module (HSM) firmware, and the interfaces it offers to hosts.
  • file ep11-wire.pdf contains documentation about the wire format which describes the protocol for communicating with an EP11 module. The EP11 Support Program provides the host library that implements this protocol.
