My team and I are working on creating a link in salesforce that will open a PEGA window. As part of the PEGA href url we are passing data via parameter which needs encrypted; it is secure data. Is there a way for salesforce to call PEGA encryption for the data? Then on the PEGA end we can decrypt it.

As per the PEGA page https://community.pega.com/knowledgebase/articles/security/encryption-pega-platform the PEGA encryption is AES256-CBC with PKCS7 padding, we use default encryption in our system.
