Citrix SecurSpaces™

Cryptography

The cryptographic algorithms Citrix SecurSpaces™ uses, and where each one applies. This page supports network security review and third-party assessment.

Data in transit

Traffic Protection
Browser and API traffic from outside the cluster HTTPS. TLS is terminated at the ingress controller.
Ingress controller to SecurSpaces services TLS
SecurSpaces service to SecurSpaces service TLS
Remote development sessions SSH

Note:

Because TLS is terminated at the ingress controller, the permitted TLS versions and cipher suites for external traffic are determined by your ingress configuration, not by SecurSpaces. Set them to meet your own policy.

Data at rest

SecurSpaces is customer-hosted, so encryption at rest for the database, persistent volumes, and etcd is your responsibility. SecurSpaces adds application-layer encryption on top of it.

Data Protection
Developer and application secrets stored in the database AES-128-GCM, when the external Vault integration is not in use
Database, persistent volumes, etcd Your infrastructure encryption, such as cloud provider KMS or encrypted Kubernetes persistent volumes

Keys and certificates

Purpose Algorithm
Application secret encryption AES-128-GCM
API tokens AES-GCM
Personal SSH identities Ed25519
SAML signing certificate, when SecurSpaces acts as the identity provider RSA 2048
Token signing JSON Web Token signing keys, held as Kubernetes Secrets
TLS X.509 certificates

SecurSpaces supports automated certificate lifecycle management for external traffic, such as cert-manager, Let’s Encrypt, or an internal PKI. It manages the certificates for internal cluster traffic itself.

Secret storage

Secret Where it is held
Developer and application secrets Encrypted in the database, or in an external HashiCorp Vault instance when that integration is enabled
Certificates, access keys, encryption keys, database credentials, token signing keys Kubernetes Secrets, stored in etcd

Kubernetes Secrets are stored in etcd, which you must protect with encryption at rest. For stronger separation, SecurSpaces works with the Secrets Store CSI Driver and External Secrets Operators.
