OIDCCacheEncrypt : cache key since key size is too large

[GFlo69]

Hi,

Note : My cache is SHM

Following the transition from version 2.4.6 to version 2.15.X I noticed the following errors:
[auth_openidc:error] [pid xxx:tid xxx[client xxx] oidc_cache_shm_get_key: could not construct cache key since key size is too large (837 >= 512)

To correct this, I implemented the OIDCCacheEncrypt option to "ON".
Is this really the correction to be made?
