Click Download CSRs. In the dialog that appears, click Download CSRs for all nodes.Prism Element downloads a
csrs.zip archive containing one CSR file per CVM node. The files use a .txt extension by default.7
Extract the
csrs.zip archive on your workstation.You can rename each file from .txt to .csr, but it is not required. The file contents are standard PEM-encoded CSRs regardless of extension.The number of CSR files in the archive equals the number of CVM nodes in the cluster. A three-node cluster produces three CSR files; a larger cluster produces more. Each CSR must be signed individually on the CryptoHub.
