Need to modify ath value in dpop payload

[bhargavmullakuru]

Issue and Steps to Reproduce

@guillaume-chervet As per my server gateway, they need ath value divide by 2 in dpop jwt payload. if possible, can we have a extra param something like makeAthHalfInJWT divide by 2 (half) in configuration itself like below. From this code...

       const configuration = this.configuration;
        const claimsExtras = {ath: await base64urlOfHashOfASCIIEncodingAsync(accessToken),};

to...

        const configuration = this.configuration;
        const athValue= await base64urlOfHashOfASCIIEncodingAsync(accessToken);
        const claimsExtras = {ath: configuration?.makeAthHalfInJWT ?  athValue.slice(0, athValue.length / 2) : athValue ,};

If you want me to send custom ath value like below, i can send it as extra param to generateDemonstrationOfProofOfPossessionAsync method.

await oidc.generateDemonstrationOfProofOfPossessionAsync( accessToken, urlSplit[0], method, ath );

Thanks in Advance.

hi @bhargavmullakuru , thank you for the issue. I'am not sure to understand why you need to devid it by 2 ? Do you have more details.

Are you using dpop inside service worker or whithout service worker?

[bhargavmullakuru]

@guillaume-chervet . I'm not using service worker in my configuration. From another gateway end they are checking dpop ath divide by 2.

Hi @bhargavmullakuru , we may can add an extras parameter so you will be able to override defaut properties by your own one.

[bhargavmullakuru]

@guillaume-chervet .. any update on this fix for new extras parameter ? 😁

[guillaume-chervet]

I will try to do it today @bhargavmullakuru :)

[bhargavmullakuru]

Okay . Thanks for your time @guillaume-chervet

I published v7.20.0-alpha.1393, but I'am not sure it will resolve your issue.

I pushed on main by mistake : https://github.com/AxaFrance/oidc-client/commit/c7793c9913128dbb82a60dff11261ca5b4749f0c But it is an alpha.

[bhargavmullakuru]

@guillaume-chervet Tried using that alpha, it was not accepting 4th parm.

[guillaume-chervet]

Sorry @bhargavmullakuru , I have created/pulished a new alpha => https://github.com/AxaFrance/oidc-client/pull/1325

7.20.0-alpha.1394

[guillaume-chervet]

Any news @bhargavmullakuru ?

[bhargavmullakuru]

It was working with that alpha version and i'm able to pass custom keys. Let me know once it's merged to main release version. Thanks for your help @guillaume-chervet
