## GrantIdGenerator Class

Default [IGrantIdGenerator](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.RandomGenerators.IGrantIdGenerator 'Abblix\.Oidc\.Server\.Features\.RandomGenerators\.IGrantIdGenerator') implementation\. Draws random bytes from a cryptographically
secure source \([System\.Security\.Cryptography\.RandomNumberGenerator](https://learn.microsoft.com/en-us/dotnet/api/system.security.cryptography.randomnumbergenerator 'System\.Security\.Cryptography\.RandomNumberGenerator') via `CryptoRandom`\)
using the byte count configured in [GrantIdLength](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.Configuration.OidcOptions#Abblix.Oidc.Server.Common.Configuration.OidcOptions.GrantIdLength 'Abblix\.Oidc\.Server\.Common\.Configuration\.OidcOptions\.GrantIdLength'), then URL\-safe Base64 encodes
the result so the resulting `grant_id` value can travel safely through HTTP transports\.

```csharp
public class GrantIdGenerator : Abblix.Oidc.Server.Features.RandomGenerators.IGrantIdGenerator
```
