public bool DeleteKeys (Func<Microsoft.AspNetCore.DataProtection.KeyManagement.IKey,bool> shouldDelete);

abstract member DeleteKeys : Func<Microsoft.AspNetCore.DataProtection.KeyManagement.IKey, bool> -> bool

Public Function DeleteKeys (shouldDelete As Func(Of IKey, Boolean)) As Boolean

Parameters

shouldDelete: Func<IKey,Boolean>

A predicate applied to each key. Returning true will cause the key to be deleted.

Returns

Boolean

True if all attempted deletions succeeded.

Exceptions

NotSupportedException

If CanDeleteKeys is false.

Remarks

Deletion is stronger than revocation. A revoked key is retained and can even be (forcefully) applied. A deleted key is indistinguishable from a key that never existed.

Generally, keys should only be deleted to save space. If space is not a concern, keys should be revoked or allowed to expire instead.

This method will not mutate existing IKey instances. After calling this method, all existing IKey instances should be discarded, and GetAllKeys should be called again.
