mc client doesnt work when passing SSE-C key

[botcheddevil]

Expected behavior

.\mc.exe cp --enc-c "public/encrypted-file.txt=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt

Should upload and encrypted file.

Actual behavior

I get the following error:

mc.exe: SSE Error. SSE key is missing.

Steps to reproduce the behavior

1. Setup minio in minikube k8s using values file

values-minio.yaml

mode: standalone
rootUser: "minio"
rootPassword: "minio123"
resources:
  requests:
    memory: 512Mi
persistence:
  enabled: true
  storageClass: "minio-retain-sc"
  accessMode: ReadWriteOnce
  size: 100Gi
existingClaim: ""
console:
  enabled: true
debug:
  enabled: true
log:
  level: debug
tls:
  enabled: true
  certSecret: minio-tls-cert-secret
  publicCrt: tls.crt
  privateKey: tls.key

.\minikube\minikube.exe start --mount --mount-string="D:\data:/minikube-host"
kubectl create ns minio-system
kubectl create -f .\charts\minio-storage-class.yaml
kubectl create -f .\charts\minio-pv.yaml
kubectl create secret tls minio-tls-cert-secret --cert=public.crt --key=private.key -n minio-system
helm install minio minio/minio --namespace minio-system -f .\charts\values-minio.yaml --debug --timeout 10m

mc --version

you need to do `--sse-c="key"

[botcheddevil]

Thank you for your response.

I tried the following variations none of them worked. Could you share the complete command?

.\mc.exe cp --sse-c="EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt
mc.exe: Invalid command usage, flag provided but not defined: -sse-c

.\mc.exe cp --enc-c "--sse-c=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt
mc.exe: SSE Error. SSE key is missing.

.\mc.exe cp --enc-c "sse-c=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt

[zveinn]

ohh..my bad
it's
--enc-c "alias/bucket/path=key"

[zveinn]

.\mc.exe cp --enc-c "public/encrypted-file.txt=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt

should be
.\mc.exe cp --enc-c "myminio/public/encrypted-file.txt=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E=" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt

Did we loosen the "raw" base 64 requirement? If not, key should be EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E.

[botcheddevil]

Yes that did work, dropping the trailing '=' thanks @klauspost @zveinn !!!

For posterity ->

.\mc.exe cp --enc-c "myminio/public/encrypted-file.txt=EACjrC0Hu8dZ0hAjZyA6TEFhC1QackD5Wk5K/ruZs3E" D:\files\encrypted-file.txt myminio/public/encrypted-file.txt

for future reference, you should also be able to use hex encoded keys.
