sops 3.8.1 (latest) encrypted files are not working in kubernetes cluster.

[alishaik1]

Hi Team,

We have a problem with the SOPS 3.8.1 version. We are generating the encrypted keys and updating them in our Kubernetes (1.25.11) cluster, which was built on Red Hat servers.

Also, we have another set of AKS (Azure Kubernetes) clusters, and it also has the 1.25.xx Kubernetes version.

3.8.1 - encrypted files are working in AKS clusters.
3.8.1 - not working in on-prem (redhat servers) kubernetes clusters.
3.7.3 - version only working in on-prem clusters.

In my current system, I installed the 3.8.1 version of sops.
why I am  not able to decrypt the file, which was generated using the 3.7.3 sops version.

sops binary is: 3.8.1
File: cps.enc.yaml (3.7.3)

Error:
sops -d cps.enc.yaml > cps.dec.yaml
Failed to get the data key required to decrypt the SOPS file.
