ASN.1 decoding of a file (Menu Individual Procedures \ Tools \ Codes)

By choosing this menu option you can decode a potential ASN.1 document via the dialog ASN.1 PIN request.

The ASN.1 structure will be displayed in a new window in ASN.1 dump format if the chosen file is an ASN.1 document indeed.

If there exists a PSE within the ASN.1 document which is also containing a certificate, then the certificate will be displayed in another window in plain text format.

A proper information dialog is displayed if CrypTool cannot find any further ASN.1 structures.

Remark:

There is a certain chance that the PSE within the chosen ASN.1 document is PIN protected. In this case a PIN request dialog will prompt you for a correct PIN to assure that only authorized persons can access the certificate.
