We have several symmetric and GPG keys and RSA certificates on the disk. Since the OS seems to have lot of secure storage facilities built into it we would like to use them and retrieve the keys on demand. I had asked this earlier but couldn't elicit any response. All these keys and certificates are externally generated using Java etc. and we need a storage facility. Users should not be able to access them or copy them without providing proper credentials. Is there such a facility available ? If there is then we need not buy another product for this.
