Subject: fix(webauthn): Increase database column for public key id
X-Git-Tag: v29.0.7rc1~23^2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fpull%2F47247%2Fhead;p=nextcloud-server.git

fix(webauthn): Increase database column for public key id

* Resolves https://github.com/nextcloud/server/issues/34476

There is no maximum length defined in the standard,
most common the length is between 128 and 200 characters,
but as we store it not in plain data but base64 encoded the length can grow about 1/3.
We had a regression with 'Nitrokey 3' which created IDs with 196 byte length -> 262 bytes encoded base64.
So to be save we increase the size to 512 bytes.
