Sander.KeyVaultCache NuGet Package

Since secrets and certificates stored in Azure Key Vault change very rarely, it is useful to cache them, as fetching is a relatively slow operation - if the Key Vault is in the same data center, it takes 100...300ms, but fetching the value from geographically distant Azure data center can take a second or even more.

With the caching, getting the value becomes a sub-millisecond operation.

KeyVaultCache simplifies the fetching and caching of the values from the Key Vault.

It is fully thread-safe, has on-demand re-fetching and supports cache expiration (entries expire after specified time).
