| Exception Name | Thrown | Description | Message |
| CryptoProviderNotFoundException | During/after configuration | No crypto provider can be found for a given alias. | The cryptographic provider could not be found for the alias: [ALIAS] |
| CryptoProviderAliasNullException | During/after configuration | The annotation has no associated alias or is null or and empty string. | Cryptographic providers require a non-null, empty alias be configured. |
| CryptoProviderMissingPublicKeyException | During/after configuration | The PublicKeyName field has not been set in the crypto provider configuration or is null or and empty string | Cryptographic providers require a non-null, empty public and key identifier (kid) be configured for the alias: [ALIAS] |
| CryptoProviderMissingSigningKeyException | During/after configuration | The SigningKeyName field has not been set in the crypto provider configuration or is null or and empty string. Required for symmetric algos. | Symmetric key cryptographic providers require a non-null, empty signing key be configured for the alias: [ALIAS] |
| CryptoProviderMissingPrivateKeyException | During/after configuration | The PrivateKeyName field has not been set in the crypto provider configuration or is null or and empty string. Required for asymmetric algos. | Asymmetric key cryptographic providers require a non-null, empty private key be configured for the alias: [ALIAS] |
