Hello,
In Brew 3.X is there any area where no other application can access if data is stored. I want to store the private key in an area where no other application can access that key.
In J2me Jsr 177 do this stuff...which store the data on sim private area...
Can anyone tell me regarding this...
Thanks in advance...

Hi,
Do you have an answer yet? I also want to store an encrypted data blob into a secure area. I don't want to use IDatabase since it's just one variable. I want to save it into a file, but are worried about security.
Thanks.

In brew if you write to a file in the app's installed folder then no other application can access that data (However the brew apploader can). If you want to be extra secure you can use ICipher / ICipher1 interfaces to encrypt that data.

Hi Skavenger,
In 3.x other app can access brew apps module directory or brew app installed directory using ifilemgr.
"fs:/~/": New for BREW 3.1, an application may access files
in another application's directory. must be a
valid class id of an application or extension. These
paths map to "fs:/mod/" where is the
module id of the module that exports . The target
module must export this path via a module ACL. See
IFILEMGR_CheckPathAccess() for more information.
Then how to secure data?
Thanks,

Default behavior is to not allow access. If you don't want other apps to access your folder, then don't create an ACL.
