OAuth (3-Legged OAuth Authorization) services  has been used for client application integration.

Noticing that authorization code is base 64 encoded. Having security concerns because base 64 code can be decoded.  Not finding any configurations to change this ?

Does OAM support any configuration changes to address above issue ?
Qn2:Can the authorization code be changed to a different configuration due to their concerns re base 64 encoding?
Qn3:The JWT token can be decoded (from Base64) and contains the principle name (prn=username) as well as an oracle field oracle.oauth.user_origin_id that holds the username.

These aren’t a security risk by themselves but could be in bulk. What controls are available to secure this information ?
