Quotas and constraints in Key Management Service - Nebius AI Cloud

Quotas

Key Management Service has quotas on the number of symmetric and asymmetric keys.

Quota name	Default value per tenant
Number of symmetric keys	100,000
Number of asymmetric keys	100,000

A deleted key counts towards the quota for 30 days after you delete it.

For details on what quotas are and how to manage them, see Quotas in Nebius AI Cloud.

Constraints

The number of manual rotations for a symmetric key can’t exceed 100. If you exceed this limit, the request fails with the HTTP 400 error. To increase this limit for a specific symmetric key, contact support.
