Class IPrivateKeyExtensions
- Namespace
- Yubico.YubiKey.Cryptography
- Assembly
- Yubico.YubiKey.dll
Extension methods for IPrivateKey to provide type-safe casting operations.
public static class IPrivateKeyExtensions
- Inheritance
-
objectIPrivateKeyExtensions
Methods
Cast<T>(IPrivateKey)
Safely casts an IPrivateKey instance to a specific derived type.
public static T Cast<T>(this IPrivateKey key) where T : class, IPrivateKey
Parameters
key
IPrivateKeyThe private key instance to cast.
Returns
- T
The private key cast to the specified type
T
.
Type Parameters
T
The target type that implements IPrivateKey.
Examples
IPrivateKey genericKey = GetPrivateKey();
RsaPrivateKey rsaKey = genericKey.Cast<RsaPrivateKey>();
// throws InvalidCastException if genericKey is not an RsaPrivateKey
Remarks
This method provides a more explicit alternative to direct casting with clearer error messages. Prefer this over unsafe casting operations when type safety is critical for cryptographic operations.
Exceptions
- InvalidCastException
Thrown when the
key
cannot be cast to typeT
. The exception message includes both the source and target type names for debugging.
