+# HashAlgorithmProviders
+
+Namespace: SimpleOTP
+
+Provides methods for registering and retrieving  providers.
+
+```csharp
+public static class HashAlgorithmProviders
+```
+
+Inheritance [Object](https://docs.microsoft.com/en-us/dotnet/api/system.object) → [HashAlgorithmProviders](simpleotp.hashalgorithmproviders)<br>
+Attributes [NullableContextAttribute](https://docs.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.nullablecontextattribute), [NullableAttribute](https://docs.microsoft.com/en-us/dotnet/api/system.runtime.compilerservices.nullableattribute)
+
+## Methods
+
+### **AddProvider(OtpAlgorithm, KeyedHashAlgorithm)**
+
+Registers a new  provider.
+
+```csharp
+public static void AddProvider(OtpAlgorithm algorithm, KeyedHashAlgorithm algorithmProvider)
+```
+
+#### Parameters
+
+`algorithm` [OtpAlgorithm](simpleotp.otpalgorithm)<br>
+The algorithm to register.
+
+`algorithmProvider` KeyedHashAlgorithm<br>
+The provider to register.
+
+### **GetProvider(OtpAlgorithm)**
+
+Retrieves a  provider.
+
+```csharp
+public static KeyedHashAlgorithm GetProvider(OtpAlgorithm algorithm)
+```
+
+#### Parameters
+
+`algorithm` [OtpAlgorithm](simpleotp.otpalgorithm)<br>
+The algorithm to retrieve.
+
+#### Returns
+
+KeyedHashAlgorithm<br>
+The  provider, or `null` if not found.
+
+### **RemoveProvider(OtpAlgorithm)**
+
+Removes a  provider.
+
+```csharp
+public static void RemoveProvider(OtpAlgorithm algorithm)
+```
+
+#### Parameters
+
+`algorithm` [OtpAlgorithm](simpleotp.otpalgorithm)<br>
+The algorithm to remove.
+
+### **IsRegistered(OtpAlgorithm)**
+
+Determines whether a  provider is registered.
+
+```csharp
+public static bool IsRegistered(OtpAlgorithm algorithm)
+```
+
+#### Parameters
+
+`algorithm` [OtpAlgorithm](simpleotp.otpalgorithm)<br>
+The algorithm to check.
+
+#### Returns
+
+[Boolean](https://docs.microsoft.com/en-us/dotnet/api/system.boolean)<br>
+`true` if the  provider is registered; otherwise, `false`.
+
+### **ClearProviders()**
+
+Removes all registered  providers.
+
+```csharp
+public static void ClearProviders()
+```
+
+**Remarks:**
+
+This method also clears default providers. Use with caution.
