#### [Abblix\.Utils](https://www.abblix.com/en/docs/api/abblix-utils 'index') ## Abblix\.Utils Namespace | Classes | | | :--- | :--- | | [AddressValidatingHttpMessageHandler](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.AddressValidatingHttpMessageHandler 'Abblix\.Utils\.AddressValidatingHttpMessageHandler') | The message\-handler half of protecting a server\-initiated request whose address came from outside: it refuses redirects and re\-checks the address immediately before every send, leaving only the policy \- which addresses are refused \- to the derived handler\. | | [ArrayExtensions](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.ArrayExtensions 'Abblix\.Utils\.ArrayExtensions') | Allocation\-explicit array helpers: each operation returns a freshly allocated array sized to the result\. Prefer these over LINQ when the caller needs a concrete `T[]` without an extra `ToArray()` step, or when copying byte buffers via [System\.Buffer\.BlockCopy\(System\.Array,System\.Int32,System\.Array,System\.Int32,System\.Int32\)](https://learn.microsoft.com/en-us/dotnet/api/system.buffer.blockcopy#system-buffer-blockcopy(system-array-system-int32-system-array-system-int32-system-int32) 'System\.Buffer\.BlockCopy\(System\.Array,System\.Int32,System\.Array,System\.Int32,System\.Int32\)') matters\. | | [Base32](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Base32 'Abblix\.Utils\.Base32') | Provides methods for encoding and decoding data using Base32 and Base32hex formats as defined in RFC 4648\.

Named with the `Flag` qualifier so it does not collide with the very common `EnumExtensions` class name used by other libraries \(e\.g\. `Fido2NetLib.EnumExtensions`\), which would surface as `CS0104` in any consumer that imports both namespaces\. | | [HexConverter](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.HexConverter 'Abblix\.Utils\.HexConverter') | Provides a static method for converting a byte array to its hexadecimal string representation\. | | [HttpServerUtility](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.HttpServerUtility 'Abblix\.Utils\.HttpServerUtility') | Provides utility methods for encoding and decoding URL tokens\. | | [ObjectExtensions](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.ObjectExtensions 'Abblix\.Utils\.ObjectExtensions') | Provides extension methods for objects to ensure non\-null values\. | | [ParametersBuilder](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.ParametersBuilder 'Abblix\.Utils\.ParametersBuilder') | Provides a builder for constructing and manipulating query strings or URI fragment parts\. | | [PrivateNetworks](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.PrivateNetworks 'Abblix\.Utils\.PrivateNetworks') | Tells an address inside the deployment's own network from one on the public internet\. | | [Result<TSuccess,TFailure>](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Result_TSuccess_TFailure_ 'Abblix\.Utils\.Result\') | Represents a result of an operation that can either succeed with a value of type [TSuccess](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Result_TSuccess_TFailure_#Abblix.Utils.Result_TSuccess,TFailure_.TSuccess 'Abblix\.Utils\.Result\\.TSuccess') or fail with a value of type [TFailure](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Result_TSuccess_TFailure_#Abblix.Utils.Result_TSuccess,TFailure_.TFailure 'Abblix\.Utils\.Result\\.TFailure')\. | | [ResultExtensions](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.ResultExtensions 'Abblix\.Utils\.ResultExtensions') | Provides extension methods for working with [Result<TSuccess,TFailure>](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Result_TSuccess_TFailure_ 'Abblix\.Utils\.Result\') types\. | | [StringExtensions](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.StringExtensions 'Abblix\.Utils\.StringExtensions') | The class provides extension methods for enhancing the functionality and ease of use of strings\. | | [UriBuilder](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.UriBuilder 'Abblix\.Utils\.UriBuilder') | A wrapper around System\.UriBuilder, providing enhanced functionality for URI manipulation, specifically for handling query strings and fragments\. | | [UriExtensions](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.UriExtensions 'Abblix\.Utils\.UriExtensions') | Helpers for adding parameters to a URI's query or fragment and for extracting standard parts \(origin, trailing slash\)\. Empty or null parameter values are dropped rather than serialized as bare keys, matching the OAuth 2\.0 / OpenID Connect convention for absent parameters\. | | [WwwAuthenticate](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.WwwAuthenticate 'Abblix\.Utils\.WwwAuthenticate') | Builds `WWW-Authenticate` challenge values: the HTTP grammar, not any one protocol's vocabulary of errors\. | | Structs | | | :--- | :--- | | [Sanitized](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.Sanitized 'Abblix\.Utils\.Sanitized') | A type that sanitizes a given string by removing control characters and escaping special characters to prevent log injection attacks\. | | Interfaces | | | :--- | :--- | | [ICertificateProvider](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.ICertificateProvider 'Abblix\.Utils\.ICertificateProvider') | Resolves an [System\.Security\.Cryptography\.X509Certificates\.X509Certificate2](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.x509certificates.x509certificate2 'System\.Security\.Cryptography\.X509Certificates\.X509Certificate2') from a logical [CertificateId](https://www.abblix.com/en/docs/api/abblix-utils/Abblix.Utils.CertificateId 'Abblix\.Utils\.CertificateId'), abstracting away the physical source \(file system, certificate store, secret manager, etc\.\)\. Implementations are expected to be thread\-safe and to surface format or access errors as [System\.InvalidOperationException](https://learn.microsoft.com/en-us/dotnet/api/system.invalidoperationexception 'System\.InvalidOperationException')\. |
