Issue/Introduction

When using the variable certificate.thumbprintSHA1 set by Extract Attributes from Certificate assertion, the result is base64 encoded.

The value presented in the manage certificate dialog however is hex-encoded. How can this value be encoded/decoded to match?

 

 

Environment

Release : 9.3

Component : API GATEWAY

Resolution

The base64 encoded value will need to be decoded as an octet-stream using the Encode/Decode Data assertion.

Once this value is obtained it can then be hex-encoded using the same assertion as seen below.
