Task #1532
Updated by Yingdi Yu about 10 years ago
Applications/Users should be able to choose the TPM that satisfy their requirements.
For example, root user may not have default OSX keychain, so that `SecTpmOsx` does not work for root user on OS X system; users may switch to SoftHSM-based TPM when it is available.
Current implementation, however, restrict apps/users to use only one TPM which is configured before building the library.
The library would be more flexible if apps/users can configure the TPM in KeyChain.
