Signature Toolkit

This tool enables graphical viewing and verifying of digitial signatures - essential for developers or support staff working within PKI.

Just drag and drop signature files (E.g. .p7b, .p7s etc) onto the tool or use the Import Data button to import base64 encoded signature data directly into the tool. It also supports the generation of signatures using machine certificates including software and smartcard certificates.

  • A path building option allows quick viewing of the certificate path
  • A data type converter allows easy conversion between binary, hexadecimal, base64 and text formats. It also allows ASN1 viewing of data.
