Steps to Reproduce
Not Applicable
Root Cause
A defect in Pegasystems’ code or rules.
Pega Cryptography operations (Encryption and Decryption) were used to protect the RequestorID in the Pega Rules cookie. Therefore, the Pega operator was unable to login.
After a Pulse change of SystemCDK, decryption of cookie fails. The Pulse change moved the Encryption and Decryption process to an inconsistent state. CurrentSystemEncryptKeyIDHash still contained the old Cryptographic Development Kit (CDK) ID.
Resolution
This issue is scheduled to be resolved in an update release of Pega 8.1.4, Pega 8.2.1, Pega and 8.3.
As a local-change, after the Pulse change, set the ActiveKeyID and CurrentSystemEncryptKeyIDHash to null.
