Expand description

Provider-origin failure reasons.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedAlgorithm

The selected algorithm is not supported by the selected lane/provider.

ProviderUnavailable

The requested provider is unavailable in this build or on this device.

RandomnessUnavailable

The selected provider could not obtain cryptographic randomness.

FallbackProhibited

Policy forbids fallback or cross-lane substitution for this operation.

PlatformUnavailable

Required platform authentication or hardware state is unavailable.

KeyExists

A persistent platform key already exists for the requested identifier.

KeyNotFound

The requested persistent platform key does not exist.

AccessDenied

Platform access-control policy denied the operation.

UserAuthenticationRequired

The platform requires user authentication before continuing.

UserCanceled

The user canceled an authentication or consent operation.

HardwareUnavailable

The requested hardware-backed security level is unavailable.

HardwareRejectedKey

The hardware provider rejected the key or operation.
